iproute2: Add FDB print and update cmds for self and master

Browse Source 
Add command to update and print FDB entries with NTF_SELF and
NTF_MASTER set.

Example usages illustrating use of 'self' to program embedded
forwarding table and 'master' to configure the forwarding table
of the bridge. Also shows 'master self' used to update both in
the same command.
