Sign patches with the cgit version

git format-patch ends each patch with the version of git that wrote it,
and the bare "cgit" that 3a00e19 left in its place said less. The
version is written as git writes its own, without the v of the tag, so
a release build signs with "cgit 2.9.0". The footer and the generator
tag still leave versions out.
