kms_frontbuffer_tracking: standardize the used FB sizes

Browse Source 
We want to make sure that both tiled and untiled buffers have the same
size for the same width/height/format. This will allow better control
over the failure paths exercised by our tests: when we try to flip
from tiled to untiled, we'll be sure that we won't execute the error
path that checks for buffer sizes.

v2: Use the new igt_calc_fb_size() instead of implementing our own
size calculation (Daniel).
v3: We can now use igt_drm_format_to_bpp() (Daniel).
