batctl: Support generic netlink for bonding command

sysfs should be avoided for new settings of network interfaces. To still provide a common configuration infrastructure, all the existing settings subcommands also have to be reimplemented via generic netlink while still using sysfs as fallback.

The bonding implementation is using the commands BATADV_CMD_SET_MESH/BATADV_CMD_GET_MESH to set/get the configuration of the u8 (boolean) BATADV_ATTR_BONDING_ENABLED attribute.
