Final cleanup of misc. dead/renamed packages
    
    Quite a few renames and replacements here. I left evince-nautilus
    in but commented out because it's disabled in the spec due to
    missing a GTK4 port, but that may well get fixed, so it seems
    better to leave a hint here that it might come back.
