subrepo: don't exclude files in .hgignore when adding to git

The previous test gave a false success because only an hg-ignored pattern was
specified.  Therefore match.files() was empty, and it fell back to the files
unknown to git.  The simplest fix is to always consider what is unknown to git,
as well as anything specified explicitly.  Files that are ignored by git can
only be introduced by an explicit mention in match.files().

# Since it's not easy to write a test that portably deals
# with files from different users/groups, we cheat a bit by
# monkey-patching some functions in the util module
