[LTP] [PATCH v1] Refactoring aiodio_append.c using LTP API

Hi Andrea,

You decided to remove file as first parameter.
That's fine ($TMPDIR/aiodio.$$/file2 as parameter used $$ to get unique
directory, but new API uses unique directory anyway), but then you should update
runtest/ltp-aiodio.part4 - remove $TMPDIR/aiodio.$$/file2.
nit: I'd just define that name with preprocessor #define.

New API has shorter variant when need to quit due missing dependencies:
TST_TEST_TCONF(), e.g.:

#else
	TST_TEST_TCONF("test requires libaio and it's development packages");
#endif

Kind regards,
