nix-prefetch-git: don't fetch everything when given a hash
It's hugely inefficient as we can't use shallow cloning (--depth=1).
This has been tested and adapted for quite a few hosts fetchgit is used on in
Nixpkgs. For those where fetching the hash directly doesn't work (most notably
git.savannah.gnu.org), we simply fall back to the old method.
