[NETFILTER]: nf_nat: autoload IPv4 connection tracking

Without this patch, the generic L3 tracker would kick in if nf_conntrack_ipv4 was not loaded before nf_nat, which would lead to translation problems with ICMP errors.

NAT does not make sense without IPv4 connection tracking anyway, so just add a call to need_ipv4_conntrack().
