changegroup: remove remaining uses of repo.manifest

The remaining uses of repo.manifest in the changegroup module are treating the
manifest excusively as a revlog, so let's replace them with instances of the
revlog directly.

This is part of dropping all dependencies on repo.manifest in favor of
repo.manifestlog.
