netfilter: xtables: support arpt_mark and ipv6 optstrip for iptables-nft only builds
Its now possible to build a kernel that has no support for the classic
xtables get/setsockopt interfaces and builtin tables.
In this case, we have CONFIG_IP6_NF_MANGLE=n and
CONFIG_IP_NF_ARPTABLES=n.
For optstript, the ipv6 code is so small that we can enable it if
netfilter ipv6 support exists. For mark, check if either classic
arptables or NFT_ARP_COMPAT is set.
