bridge: fdb: add flush [no]extern_learn entry matching
Add flush support to match entries with or without (if "no" is
prepended) extern_learn flag.
Examples:
$ bridge fdb flush dev br0 extern_learn
This will delete all extern_learn entries in br0's fdb table.
$ bridge fdb flush dev br0 noextern_learn
This will delete all entries except the ones with extern_learn flag in
br0's fdb table.
