lib/igt_fb: Generalize the slow read from gtt mmap handling
Make the handling of slow gtt mmap reads generic, and extend it to
the pixman converter. Makes the pixman path a bit faster.
With testing just XRGB8888 and XBGR8888 on KBL:
$ time kms_plane --r pixel-format-pipe-A-planes
- real 0m18,757s
+ real 0m2,635s
v2: Use the original src buffer if the malloc fails (Chris)
Drop the duplicated comment about things being slow
