[eog] Don't call gdk_threads_init()

[Felix Riemann <friemann src gnome org>]

commit 757128bc3792cca59115df3b956bffedd3732214
Author: Lars Uebernickel <lars uebernickel canonical com>

    Don't call gdk_threads_init()
    
    Accessing gdk from outside the main thread is deprecated.
    
    This also replaces an occurence of gdk_threads_add_idle_full() with an
    idle source that is dispatched to the main thread.
