Remove IPX over IP tunneling pieces from ifconfig(8), omitted portion of

previous commit:

  Remove IPX over IP tunneling support, which allows IPX routing over IP
  tunnels, and was not MPSAFE.  The code can be easily restored in the
  event that someone with an IPX over IP tunnel configuration can work
  with me to test patches.

  This removes one of five remaining consumers of NET_NEEDS_GIANT.
