[PATCH] netfilter: xt_tee: fix calling nf_dup_ipv6

[PATCH] netfilter: xt_tee: fix calling nf_dup_ipv6

[Arnd Bergmann]

Now that we can enable the NETFILTER_XT_TARGET_TEE option without supporting
TEE on ipv6, we get a build error with NETFILTER_XT_TARGET_TEE=y, IPV6=y and
IP6_NF_IPTABLES=n:

ERROR: "nf_dup_ipv6" [net/netfilter/xt_TEE.ko] undefined!

I previously submitted another patch that fixes the same symptom for the
case of IP6_NF_IPTABLES=m, but missed the fact that there are still
similarly broken configurations.

Fixes: 35bf1ccecaaa ("netfilter: Kconfig: Change IPv6 select dependencies")
