aio test added

[Andreas Jaeger]

Uli, the bug report was for li_listio (LIO_NOWAIT, arr, 1, NULL).
Your testcase is for LIO_WAIT.  I've rewritten tst-aio2 slightly to
test also LIO_NOWAIT and named the new file tst-aio3.

I've commited the appended patch.

	* rt/tst-aio3.c: New file, slightly modified version of tst-aio2.
	* rt/Makefile: Add rules to build and run tst-aio3.
