color-noop: add stock color profile

Browse source 
In the next commit we introduce a function to get the stock sRGB color
profile from the color-manager, so mock a stock color profile in the
color-noop.

It has no valid content, but should make callers happy. This is safe to
do because the color profile is opaque, and only color-noop itself
should have access to its content.

color-lcms already has a stock sRGB color profile, so we don't have
to do anything there.
