Bruno Pinto 9cc8ee5a82 Stash does not support --git-dir ...

Stash is a shell script that does not support `--git-dir`, not even on
latest versions. We need to use `git -C` which was only added on recent
versions of `git`.

`omf update` will fail in case omf need needs to run `git stash` and
git is not compatible.
