rhg: fix race when an ambiguous file is deleted on disk

There are two places in the status code where we handle files whose status
we are unsure of based off of metadata alone: this one is the first one to
actually disambiguate, and the second one is later in the code (but updated
in the previous commit) for files that are actually clean to update the
dirstate. Since there is a chance that the contents have changed between
those two moments, we need to stat the files again, since re-using the old
stat could lie about the clean state of the file.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install::

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing::

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.

Notes for packagers
===================

Mercurial ships a copy of the python-zstandard sources. This is used to
provide support for zstd compression and decompression functionality. The
module is not intended to be replaced by the plain python-zstandard nor
is it intended to use a system zstd library. Patches can result in hard
to diagnose errors and are explicitly discouraged as unsupported
configuration.
