[gtk+] a11y: Remove AtkSelection implementation from combobox

[Benjamin Otte <otte src gnome org>]

commit 7cecc8e524f9ac3825622e10f8a98f5e01ac4727

    a11y: Remove AtkSelection implementation from combobox
    
    AtkSelection requires that the immediate children of the object are the
    selectable items. The combobox however is implemented with just 1 child:
    The popup menu.
    
    The popup menu is implementing the selectable interface.
    
    Test are updated to reflect this change.
