mmsg.test: fix regression introduced by commit v4.11-138-g6e815ce
This fixes the test on platforms where both __NR_sendmmsg and
HAVE_SENDMMSG are defined but the former is not implemented by the
kernel and the second is implemented as an indirect syscall.
* tests/mmsg.c (LENGTH_OF): New macro.
(send_mmsg, recv_mmsg): Print expected output in case of ENOSYS.
(main): Redirect stdout to a new descriptor. Use LENGTH_OF.
Print expected output.
* tests/mmsg.test: Update.
