[gnome-control-center] universal-access: Replace GtkHBox and GtkVBox

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

commit 86413dc6d5532abe0410e1893e4f97cf7a6143d2
Author: Georges Basile Stavracas Neto <georges stavracas gmail com>

    universal-access: Replace GtkHBox and GtkVBox
    
    We can simply use a GtkBox and set the orientation property.
    Since this property defaults to 'horizontal', we actually
    only need to set it when replacing GtkVBox.
