batman-adv: add broadcast duplicate check
When multiple backbone gateways relay the same broadcast from the backbone into the mesh, other nodes in the mesh may receive this broadcast multiple times. To avoid this, the crc checksums of received broadcasts are recorded and new broadcast packets with the same content may be dropped if received by another gateway.
