pack: add repository argument to prepare_packed_git

Add a repository argument to allow prepare_packed_git_mru callers to
be more specific about which repository to handle. This is a small
mechanical change; it doesn't change the implementation to handle
repositories other than the_repository yet.

Callers adapted using contrib/coccinelle/packed_git.cocci.

As with the previous commits, use a macro to catch callers passing a
repository other than the_repository at compile time.
