bridge: fdb: support match on [no]router flag in flush command

Browse Source 
Extend "fdb flush" command to match entries with or without (if "no" is
prepended) router flag.

Examples:
$ bridge fdb flush dev vx10 router
This will delete all fdb entries pointing to vx10 with router flag.

$ bridge fdb flush dev vx10 norouter
This will delete all fdb entries pointing to vx10, except the ones with
router flag.
