[PATCH libaio 28/28] harness: Skip the test if io_pgetevents() is not implemented

Either the kernel or the syscall wrapper will return -ENOSYS when this
syscall is not implemented. So we should cope with this in the test
suite and SKIP the test case.

This is currently the case for alpha and ia64, even though they have
already been wired up very recently in the kernel mainline.
