[gtk] Avoid warnings

[Matthias Clasen <matthiasc src gnome org>]

commit e0771a54a2102c80750beba2e643310118e98963
Author: Matthias Clasen <mclasen redhat com>

    Avoid warnings
    
    When generating introspection data, we instantiate types without
    calling gtk_init, so make sure that extension points are registered
    before the type is trying to implement them.
