util/nvmutil: Do not allow /dev/urandom on OBSD

There, we use arc4random_buf which does not directly
access /dev/urandom on BSD; it uses a userspace method
instead, which bypasses this.

This is therefore much more restrictive, which is
exactly the point of unveil(2) and pledge(2); restrict
your program's operation while ensuring that it has what
it needs, to help with debugging and prevent common bugs.
