Ok.

I think it's bogus to reseve system calls for everybody even when it
makes no sense.

But it's also pretty moot, since I think the whole system call has to go away.

All it is is an odd wrapper around mmap() anyway, and it's a useful
enough thing *outside* of getrandom() that I pretty much guarantee it
will be used for other things than vgetrandom anyway.
