    gio: fix binding for GActionGroup.list_actions()
    
    vapigen was detecting
    
      gchar ** g_action_group_list_actions (GActionGroup *action_group);
    
    as
    
      public abstract unowned string list_actions ();
    
    Add some metadata to clear that up and regenerate the vapi.
