[PATCH i-g-t] lib/igt_chamelium: Create pixman image with bytes per pixel, not bits

[Paul Kocialkowski]

The pixman_image_create_bits function expects bytes per pixels as fifth
argument, not bits per pixels.

This divides the PIXMAN_FORMAT_BPP macro's result by 8 to get it in
bytes per pixels instead of bits per pixels.
