[acl] Remove Ethertype from L3V6 qualifiers (sonic-net#1433)

This change was already done for MIRRORV6 tables a while back. ETHER_TYPE is unnecessary for V6 tables as the ethertype should always be the same (86DD) for IPv6 traffic. Additionally, this qualifier breaks IPv6 support on some platforms (e.g. Mellanox).
