extensions: libebt_redirect: prevent translation

The redirect target in ebtables do two things: 1. set skb->pkt_type to
PACKET_HOST, and 2. set the destination mac address to the address of
the receiving bridge device (when not used in BROUTING chain), or the
receiving physical device (otherwise). However, the later cannot be
implemented in nftables not given the translated mac address. So it is
not appropriate to give a specious translation.

This patch disables the translation to prevent possible misunderstanding.
