[Intel-gfx] [PATCH i-g-t] lib/draw: Align mmap requests to page boundaries

> Since we trust fb->size as either calculated by calc_fb_size() or the
> supplied by the user, it invariably isn't page aligned. The mmap
> routines and ioctls only deal in pages...
> 
> Not sure if fb->size should be page aligned, but that may break
> some other drawing tests, so opt to just fix up the mmap requests.
