lib/igt_fb: Add support for C8 pixel format
Expose C8 support by utilizing pixman's rgb332 support.
By using rgb332 we don't have to worry too much about
how to populate the LUT, though for now we still leave
that responsibility to individual tests. If desired we
could make igt_kms generate a suitable LUT when the test
itself didn't bother. But meh for now.
