[PATCH] selftests/powerpc: Fix exit status of pkey tests

[Sandipan Das <sandipan@linux.ibm.com>]

Since main() does not return a value explicitly, the
return values from FAIL_IF() conditions are ignored
and the tests can still pass irrespective of failures.
This makes sure that we always explicitly return the
correct test exit status.
