wayland: assume all image description is parametric until icc_file event

If we used get_preferred_parametric to get this image description, then
it is guaranteed to be parametric. If we used get_preferred to get this
image description, then it may or may not be parametric depending on the
compositor. If we receive an icc_file event, then the image description
is not parametric.
