Revert "libgimpcolor: fix call to cmsCreateProofingTransform()."

This reverts commit f7e7f396aa.

See issue #8269.
For GIMP 2.10, I'll just revert this commit so that we get back to pre-2.10.32
situation. ~~For 3.0, we'll try to do something better.~~

-> Let's delay improving the situation even for GIMP 3.0, in which case
it's better to at least keep the same render as for the 2.10 series and
avoid confusion. I'll take more time after release to study better the
situation and see what we should actually do.
