For ICC profile validation, have cups id iteself as DeviceN

Give the range of color spaces and models that cups supports, we can't
reasonably provide (or expect others to provide) output ICC profiles for all
cases.

For the purpose of profile validation, have it claim to be DeviceN and benefit
from the extra tolerance in profiles allowed for that class of device.
