netfilter: fix NETFILTER_XT_TARGET_TEE dependencies
With NETFILTER_XT_TARGET_TEE=y and IP6_NF_IPTABLES=m, we get a link error when referencing the NF_DUP_IPV6 module: net/netfilter/xt_TEE.o: In function `tee_tg6': xt_TEE.c:(.text+0x14): undefined reference to `nf_dup_ipv6' The problem here is the 'select NF_DUP_IPV6 if IP6_NF_IPTABLES' that forces NF_DUP_IPV6 to be =m as well rather than setting it to =y as was intended here. Adding a soft dependency on IP6_NF_IPTABLES avoids that broken configuration.
