osx: override default exclude filter for pkgbuild

To quote `man 1 pkgbuild`:

     --filter filter-expression
                 By default, --root will include the entire contents of the
                 given root-path in the package payload, except for any .svn
                 or CVS directories, and any .DS_Store files. You can override
                 these default filters by specifying one or more --filter
                 options. Each filter-expression is an re_format(7)
                 ``extended'' expression: any path in the root which matches
                 any of the given expressions will be excluded from the pack-
                 age payload. (Note that specifying even one --filter inhibits
                 the default filters, so you must respecify the default fil-
                 ters if you still want them to be used.)

It turns out the default filter these days *also* includes .git and
.hg. Notice how that filter expression is a regular expression?  That
(presumably unintentionally) prevents a file named "chg" or "_hg" from
getting included in the distribution. Many many thanks to spectral@
for trying to include a _hg file which led us to figure this bug out.

Bug filed with Apple for this as rdar://problem/32437369, mentioning
both the gap in documentation and the wrong defaults.

'''browse command output with an external pager (DEPRECATED)

Forcibly enable paging for individual commands that don't typically
request pagination with the attend-<command> option. This setting
takes precedence over ignore options and defaults::

  [pager]
  attend-cat = false
