Fix -e output for FDDI, Token Ring, and IP-over-Fibre Channel.

Fix -e output for FDDI, Token Ring, and IP-over-Fibre Channel.

Print them the same way other headers are printed ("src > dst, length l").

For FDDI, always print the frame control field symbolically

For Token Ring, print the AC and FC fields unless the -q flag was given,
just as we do for the FC field for FDDI.
