[gimp/goat-invasion] app: use gimp_drawable_apply_operation_to_buffer() in gimp_layer_flatten()

    app: use gimp_drawable_apply_operation_to_buffer() in gimp_layer_flatten()
    
    and not gimp_drawable_apply_operation_to_tiles() because that would
    guess the wrong Babl format for the new tiles if the image is indexed.
