tests/gem_userptr_blits: subtests for MAP_FIXED mappings of regular BO
When the memory backing the userptr object is released by the user, but the
BO itself is not closed, it's possible to trigger recursive deadlock
caused by operations done on different BO mapped in that region.
Testcases are simulating such behaviour by using MAP_FIXED mmap flag.
