Use relations_with() in getilists()

No functional change, even though this changes rel[intruder] from
NEUTRAL to ALLIED.  Uses of rel[]:

* getilists() and ac_encounter() compare rel[cn] to HOSTILE.  No
  change, because NEUTRAL and ALLIED are both greater than HOSTILE.

* ac_encounter() compares rel[cn] to ALLIED, but only when cn !=
  plane_owner.  Because it passes plane_owner as argument for
  getilists() parameter intruder, rel[cn] can't refer to the changed
  element of rel[] here.

The new value of rel[plane_owner] permits simplifying cn ==
plane_owner || rel[cn] == ALLIED to just rel[cn] == ALLIED.
