git: move async_cat reference to PublicInbox::Git

Trying to avoid a circular reference by relying on $ibx object
here makes no sense, since skipping GitCatAsync::close will
result in an FD leak, anyways.  So keep GitAsyncCat contained to
git-only operations, since we'll be using it for Solver in the
distant feature.
