Add git-server to docker-compose

To make a githook that can run on alpine images (using musl) they
need to be cross-compiled. Then it became apparent that the githook
binary was pulling in all the same dependencies as the server was.

This is not good, but apparently also not something Rust/Cargo has
figured out. RFC:s has been shutdown. workspace might be an option
but then I probably need to also add a "code shared by both githook
and server" library that both can link. Problem for another day.
