tests: deal with some git versions sending status messages to stderr

git-1.8.4.2 on Fedora 20 will send messages like
  Cloning into 'X'...
  done.
to stderr.

The test cases for git subrepos tricks hg into invoking git. Stdout is muted,
stderr isn't. Muting stderr in hg do not sound like a good idea. Instead we do
it in the tests.
