    gs-content-rating: Drop all content rating code if as-glib is new enough
    
    This code has all been moved into appstream-glib 0.7.18
    (https://github.com/hughsie/appstream-glib/pull/364), so gnome-software
    can ship some compatibility defines until it has a hard dependency on
    the new appstream-glib, at which point `gs-content-rating.[ch]` can be
    deleted.
    
    gnome-software can’t depend on appstream-glib > 0.7.14 yet, as that’s
    what’s in Debian Stable, which is used for CI.
