bitbake/fetch2/git: Ensure .gitconfig file is ignored

If a user has a ~/.gitconfig file, git fetch --all will reference it. To avoid
this we should run git fetch with an explicit url telling it to fetch all
references (which includes tags).

I'm assured this means git won't reference the file, see the discussion on the
git mailing list (subject Overriding ~/.gitconfig using GIT_CONFIG).
