gdk/wayland: Don't notify of settings changes on startup. 
I was profiling Firefox startup on Wayland, and I realized that we were
doing too much work because we get extra settings changed events, posted
from here:

    #13 main(int, char**, char**) (argc=<optimized out>, argv=<optimized out>, envp=<optimized out>) at /home/emilio/src/moz/gecko-6/browser/app/nsBrowserApp.cpp:445

We shouldn't post events for a screen we're just creating, because it
can make apps do too much work during startup. X11 had code for this.
