intel/blorp: Fix faked RGB image alignment on XeHP

Browse source 
On XeHP, NPOT and POT formatted surfaces will use different image
alignment units when emitting surface states. When BLORP fakes an RGB
image as RED, update the image alignment to prevent assert failures when
emitting surface states.
