Enable the new userfaultfd syscall in the generic syscall table.
Briefly tested on arm64 with the selftest from the tools directory.

Can you update the selftest too, please? Last time I looked at that it had
typo for the powerpc check and looked pretty unloved...

I actually sent two patches doing that 10 minutes before that one, but I
forgot to CC: you on this:

Feel free to chime into the discussion ;-)

Cheers,
Andre.
