scheduler/colorman.c: Fix memory leak during creating color profile

Since the array profiles is set to use strdup() as a copy function, we
don't have to use strdup() on the element which is passed as parameter
of cupsArrayAdd() - using the strdup() as we used till now causes
memory leak.

Reproducer is the same as #813
