tipc: add InfiniBand media type

Add InfiniBand media type based on the ethernet media type.

The only real difference is that in case of InfiniBand, we need the entire
20 bytes of space reserved for media addresses, so the TIPC media type ID is
not explicitly stored in the packet payload.

Sample output of tipc-config:

# tipc-config -v -addr -netid -nt=all -p -m -b -n -ls
