[LTP] [PATCH v4 2/3] aio_tio: convert to new lib

[Petr Vorel <pvorel@suse.cz>]

Hi Matthias,

> Convert to the new test lib and perform various cleanups.
> Also refactor the test definition for readability.

Thanks for your work, whole patchset pushed, with following fixes and further
cleanup.

Defining struct tst_test after HAVE_LIBAIO guard lead to build failures
on distros without libaio.


Kind regards,
Petr
