Subject: pop3d: enable native fcntl locks on all *BSDs

...as we've already done for the simpler case of mbox locking in lei.
I've just confirmed NetBSD and OpenBSD share the same "struct flock"
with FreeBSD, and assume DragonflyBSD is the same.  sizeof(pid_t) == 4
in all places I've checked, and it's unlikely we'll need 64-bit
pid_t any time soon...
