The value of __NR_userfaultfd was changed to 282 when
asm-generic/unistd.h was included. It makes the test to fail every time
as the correct number of this syscall on x86_64 is 323. Fix the header
to asm/unistd.h.


"please elaborate every time" - I just built on my x86_64 and built
just fine. I am not saying this isn't a problem, it is good to
understand why and how it is failing before making the change.

Fixes: a5c6bc590094 ("selftests/mm: remove local __NR_* definitions")
