(Merge 3.3) test_faulthandler: skip test_read_null() on AIX
AIX maps the first page of memory at address zero as valid, read-only. Reading
NULL is not a fault on AIX. This is utilized by IBM compiler optimizations.
One speculatively can indirect through a pointer which may be null without
first testing if null and defer the test before using the value.
