[gtk+/wip/background-rework: 4/4] window: don't override background every style_updated()

    window: don't override background every style_updated()
    
    This queues an unnecessary resize on the toplevel, and is not needed
    anymore, now that GtkWidget does not call
    gtk_style_context_set_background() on the window's GdkWindow anymore.
