Subject: [PATCH] netfilter: fix dependency issues between IPv6 defragmentation and ip6tables

commit f6318e558806c925029dc101f14874be9f9fa78f fix some related issue
when ip6tables is enabled. But when IP6_NF_IPTABLES is disabled and
NETFILTER_XT_TARGET_TPROXY is enabled. We will meet build failure with
"net/built-in.o: In function `tproxy_tg_init':
net/netfilter/xt_TPROXY.c:588: undefined reference to `nf_defrag_ipv6_enable'
"
So this patch change the Kconfig as ipv4 does.

 	  This option adds a `TPROXY' target, which is somewhat similar to
 	  REDIRECT.  It can only be used in the mangle table and is useful
