Add flush support to match entries with or without (if "no" is
prepended) sticky flag.

Examples:
$ bridge fdb flush dev br0 sticky
This will delete all sticky entries in br0's fdb table.

$ bridge fdb flush dev br0 nosticky
This will delete all entries except the ones with sticky flag in
br0's fdb table.
