[NETFILTER]: nf_nat: autoload IPv4 connection tracking

Browse Source 
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().
