ike: Allow creation of internally used payloads

Since 42e0a317c64b ("ike: Only parse payloads valid for the current IKE
version") payload types are checked before creating objects.  This check
failed for internally used payload types (e.g. proposal substructures),
which have a type >= 256, i.e. outside the IKE payload type range.
