[gtk/wip/otte/boxes: 38/52] container: Drop gtk_container_check_resize()

[Benjamin Otte <otte src gnome org>]

commit e0ec5caaf868e9a33ec0f5f5bc5b71db99c4a2c4
Author: Benjamin Otte <otte redhat com>

    container: Drop gtk_container_check_resize()
    
    Instead, hardcode GtkWindow for now.
    The code for non-windows was entirely broken.
