[gtk+/gtk-3-16] testgmenu: use the menu binding code

[Matthias Clasen <matthiasc src gnome org>]

commit 0002a8a604905254f5d2e0a25bcb17fc53af8979
Author: Ryan Lortie <desrt desrt ca>
Date:   Mon Jul 6 09:40:48 2015 -0400

    testgmenu: use the menu binding code
    
    The menu tracker does a better job of this than we can, so move over to
    using it instead.
    
    This fixes issues with './testgmenu --import' not properly displaying
    the language submenu.
