pf: remove unused ioctls.

Several ioctls are unused in pf, in the sense that no base utility
references them.  Additionally, a cursory review of pf-based ports
indicates they're not used elsewhere either.  Some of them have been
unused since the original import.  As far as I can tell, they're also
unused in OpenBSD.  Finally, removing this code removes the need for
future pf work to take them into account.
