batman-adv: Add distributed_arp_table mesh genl configuration

The mesh interface can use a distributed hash table to answer ARP requests without flooding the request through the whole mesh. The BATADV_CMD_SET_MESH/BATADV_CMD_GET_MESH commands allow to set/get the configuration of this feature using the BATADV_ATTR_DISTRIBUTED_ARP_TABLE_ENABLED attribute. Setting the u8 to zero will disable this feature and setting it to something else is enabling this feature.
