[vs]Preventing ebtables cfg to be applied on vs (#11585)

*Preventing ebtables rules to be applied on KVM image. The ebtables rules in SONiC are added to prevent ARP as well as L2 forwarding to be blocked in linux kernel since the hardware will take care of the actual L2 forward. However this is not the case with KVM where linux needs to forward even L2 packets
