Handle including git subdir like "ubuntu.noble/languages"

Previously, to check out seeds in Bazaar repos, we use
notations like "ubuntu.noble/languages" to indicate checking
out "languages" subdirectory inside "noble" branch.

This workaround is to ensure the backward compatibility with
bzr repos. However, this implies we cannot include "/" in
git branch name, otherwise it will be recognized as a
subdirectory name in germinate.

Git itself does not provide a convenient function to check
out a subdirectory of a repo, therefore we remove the path
and attempt to check out the entire repo, which it might be
previously checked out.
