xt_TEE.c needs nf_dup_ipv6.c to support ipv6 packet duplication.
So that if xt_TEE is enabled, nf_dup_ipv6 will be automatically selected.
But there is build failure scenario.
test config:
CONFIG_NETFILTER_XT_TARGET_TEE=y
CONFIG_NF_DUP_IPV6=m
compile result:
net/netfilter/xt_TEE.o: In function `tee_tg6':
net/netfilter/xt_TEE.c:57: undefined reference to `nf_dup_ipv6'
This patch forces to avoid above config.

This option adds a "TEE" target with which a packet can be cloned and
this clone be rerouted to another nexthop.
