lime-proto-batadv: get real and stop trying to push OGMs over ethernet

issues include
 * fragmentation (since mtu is not enough) which impacts performance,
in some cases severely (i.e. when the ethernet link is wirelessly bridged)
 * instability (racy conditions, it seems) with BLA2
 * spurious warnings about 'received packet with own address' on br-lan
 * complicates things when two different clouds are accidentally connected
by an plain ethernet cable between them
