    Make ordering for overridden interface properties consistent
    
    g_object_class_list_properties tries to sort the returned list of
    paramspecs by 'type depth' and param_id. But all the overridden
    interface properties have a param_id of 0, so they come out in
    a random order.
    
    Bug 628253.
