[LTP] [PATCH 3/3] syscalls/io_submit: Convert libaio wrapper function to kernel syscall

NOTE: if most of the test the same, with little help of #ifdef and maybe 1-2
macros we can have single source for both variants (compiling 2 binaries).
See setdomainname and sethostname tests (setdomainname.h).

Kind regards,
Petr
