setup: ignore 'not importing' warnings during version detection

Python will issue an ImportWarning when seeing 'import locale' if
there is a locale/ directory present without a __init__.py file.

The warning is silent by default, but it somehow shows up anyway on
Windows when setup.py executed hg. The warning causes runcmd to panic
since it sees output on stderr.

This patch ignores warnings on stderr about not importing a package.

Mercurial allows you to customize output of commands through
templates. You can either pass in a template from the command
line, via the --template option, or select an existing
template-style (--style).

You can customize output for any "log-like" command: log,
outgoing, incoming, tip, parents, heads and glog.

Three styles are packaged with Mercurial: default (the style used
when no explicit preference is passed), compact and changelog.
Usage::

    $ hg log -r1 --style changelog

A template is a piece of text, with markup to invoke variable
expansion::

    $ hg log -r1 --template "{node}\n"

Strings in curly braces are called keywords. The availability of
keywords depends on the exact context of the templater. These
keywords are usually available for templating a log-like command:

:author:    String. The unmodified author of the changeset.
:branches:  String. The name of the branch on which the changeset
            was committed. Will be empty if the branch name was
            default.
:date:      Date information. The date when the changeset was
            committed.
:desc:      String. The text of the changeset description.
:diffstat:  String. Statistics of changes with the following
            format: "modified files: +added/-removed lines"
:files:     List of strings. All files modified, added, or removed
            by this changeset.
:file_adds: List of strings. Files added by this changeset.
:file_mods: List of strings. Files modified by this changeset.
:file_dels: List of strings. Files removed by this changeset.
:node:      String. The changeset identification hash, as a
            40-character hexadecimal string.
:parents:   List of strings. The parents of the changeset.
:rev:       Integer. The repository-local changeset revision
            number.
:tags:      List of strings. Any tags associated with the
            changeset.
:latesttag: String. Most recent global tag in the ancestors of this
            changeset.
:latesttagdistance: Integer. Longest path to the latest tag.

The "date" keyword does not produce human-readable output. If you
want to use a date in your output, you can use a filter to process
it. Filters are functions which return a string based on the input
variable. You can also use a chain of filters to get the desired
output::

   $ hg tip --template "{date|isodate}\n"
   2008-08-21 18:22 +0000

List of filters:

:addbreaks:   Any text. Add an XHTML "<br />" tag before the end of
              every line except the last.
:age:         Date. Returns a human-readable date/time difference
              between the given date/time and the current
              date/time.
:basename:    Any text. Treats the text as a path, and returns the
              last component of the path after splitting by the
              path separator (ignoring trailing separators). For
              example, "foo/bar/baz" becomes "baz" and "foo/bar//"
              becomes "bar".
:stripdir:    Treat the text as path and strip a directory level,
              if possible. For example, "foo" and "foo/bar" becomes
              "foo".
:date:        Date. Returns a date in a Unix date format, including
              the timezone: "Mon Sep 04 15:13:13 2006 0700".
:domain:      Any text. Finds the first string that looks like an
              email address, and extracts just the domain
              component. Example: ``User <[e-mail]>`` becomes
              ``example.com``.
:email:       Any text. Extracts the first string that looks like
              an email address. Example: ``User <[e-mail]>``
              becomes ``[e-mail]``.
:escape:      Any text. Replaces the special XML/XHTML characters
              "&", "<" and ">" with XML entities.
:fill68:      Any text. Wraps the text to fit in 68 columns.
:fill76:      Any text. Wraps the text to fit in 76 columns.
:firstline:   Any text. Returns the first line of text.
:nonempty:    Any text. Returns '(none)' if the string is empty.
:hgdate:      Date. Returns the date as a pair of numbers:
              "1157407993 25200" (Unix timestamp, timezone offset).
:isodate:     Date. Returns the date in ISO 8601 format:
              "2009-08-18 13:00 +0200".
:isodatesec:  Date. Returns the date in ISO 8601 format, including
              seconds: "2009-08-18 13:00:13 +0200". See also the
              rfc3339date filter.
:localdate:   Date. Converts a date to local date.
:obfuscate:   Any text. Returns the input text rendered as a
              sequence of XML entities.
:person:      Any text. Returns the text before an email address.
:rfc822date:  Date. Returns a date using the same format used in
              email headers: "Tue, 18 Aug 2009 13:00:13 +0200".
:rfc3339date: Date. Returns a date using the Internet date format
              specified in RFC 3339: "2009-08-18T13:00:13+02:00".
:short:       Changeset hash. Returns the short form of a changeset
              hash, i.e. a 12-byte hexadecimal string.
:shortdate:   Date. Returns a date like "2006-09-18".
:strip:       Any text. Strips all leading and trailing whitespace.
:tabindent:   Any text. Returns the text, with every line except
