Handle shallow checkout of SHA1 pinned repos

Browse Source 
When doing a shallow checkout SHA1 pinned repos with repo init --depth=1 and
repo sync -c, repo would try to fetch only some reference and fail if the exact
SHA1 repo was missing.
Instead, when depth is set, fetch only the specific commit.
