[LTP] [PATCH] sched_{set, get}attr: Call the syscalls via tst_syscall()

You're right. The binaries were built against a newer Bionic, which
provides sched_setattr() and sched_getattr(), and then run on devices
with an older libc that lacks them. That's a mismatch in our build and
test setup, not something the tests should work around.

Please drop this patch, and sorry for the noise.

Thanks,
Wake
