Maybe to be safe to check also TST_RET?

if (TST_RET == -1 && TTERRNO == ENOSYS)

Maybe (after the release) we could add new macro to tst_test_macros.h
similar to TEST(), which would do test like this (variant of tst_syscall()
macro). We already have 10 tests which do this manually.

Kind regards,
Petr
