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.
