    GtkListBox: Remove add_to_scrolled()
    
    Now that we automatically set up the focus_vadjustment we only
    need the adjustment to handle the page-up/down scroll length correctly.
    
    We use parent_set to automatically pick up the adjustment from a
    scrollable (i.e. viewport) parent which makes add_to_scrolled useless, so
    it can be removed.
