[PATCH v2 1/2] git: only fetch requested tag

[Felix Moessbauer]

On git clones, the fetching of tags need to be explicitly requested.
When requesting to fetch a tag, we previously fetched all tags and just
checked out the needed one. However, it is sufficient to only fetch the
requested one.

This is a preparation to support shallow clones.
