[gtk+] Drop gdk_keymap_get_default()

[Matthias Clasen <matthiasc src gnome org>]

commit fd85ff0c7a8798703ccb6d7bce17cfee21a5479e
Author: Matthias Clasen <mclasen redhat com>

    Drop gdk_keymap_get_default()
    
    It is better to use the explicit keymap getter - the
    default display may not even use the current gdk backend.
