Git: Make dependency on Emacs optional, per Yuri's request.

This works by looking for `git.useEmacs', a boolean, in the user's Nixpkgs
config file.  The default is `true' since it's only a build-time dependency
and most users are expected to install the pre-compiled substitute, which
doesn't pull Emacs.
