    listitemwidget: Claim gesture when activating
    
    Claim the gesture when we are activating a list item.
    
    Otherwise we end up with double activations in
    columnviews: first GtkColumnViewCell handles
    the event, and then GtkListItemWidget handles
    it again.
    
    Fixes: #4015
