This allows them to stop guessing the network namespace with pick_net.

While testing various Kconfig options on another issue, I found that
the following one triggers as well on allmodconfig and nf_conntrack
disabled:
net/ipv4/netfilter/nf_dup_ipv4.c: In function ‘nf_dup_ipv4’:
net/ipv4/netfilter/nf_dup_ipv4.c:72:20: error: ‘nf_skb_duplicated’ undeclared (first use in this function)
if (this_cpu_read(nf_skb_duplicated))
[...]
net/ipv6/netfilter/nf_dup_ipv6.c: In function ‘nf_dup_ipv6’:
net/ipv6/netfilter/nf_dup_ipv6.c:66:20: error: ‘nf_skb_duplicated’ undeclared (first use in this function)
if (this_cpu_read(nf_skb_duplicated))
Fix it by including directly the header where it is defined.

This new expression uses the nf_dup engine to clone packets to a given gateway.
Unlike xt_TEE, we use an index to indicate output interface which should be
fine at this stage.
Moreover, change to the preemtion-safe this_cpu_read(nf_skb_duplicated) from
nf_dup_ipv{4,6} to silence a lockdep splat.
Based on the original tee expression from Arturo Borrero Gonzalez, although
this patch has diverted quite a bit from this initial effort due to the
change to support maps.

Extracted from the xtables TEE target. This creates two new modules for IPv4
and IPv6 that are shared between the TEE target and the new nf_tables dup
expressions.
