Subject: [PATCH libaio 1/3] harness: Print better error messages on error
 conditions in 22.t

These should help diagnose problems when dealing with error failures.
In particular this helped distinguish the problem with io_pgetevents()
not being implemented and it failing due to the sigset_t layout bug.
