I would say that doing #ifdef __NR_* in test source to disable it is
wrong to begin with.

Doing 'git grep ifdef __NR' shows only socketcall, set_robust_list and
timerfd tests.

The timerfd tests include lapi/syscalls.h already and uses ltp_syscall()
so that shouldn't break. I guess we can safely remove the ifdef there as
well.

The set_robust_list includes the old test.h so thi change to
tst_device.h should not affect it either.

So as far as I can tell the only thing that breaks are the socketcall
tests and I guess that the actual fix would be using tst_syscall()
instead of syscall() and we can remove the ifdefs as well.
