[PATCH iptables 1/2] iptables-translate: print nft command for each expand rules via dns names

[Pablo Neira Ayuso <pablo@netfilter.org>]

We have to print nft at the very beginning for each rule that rules from
the expansion, otherwise the output is not correct:

 # iptables-translate -I INPUT -s yahoo.com
 nft insert rule ip filter INPUT ip saddr 206.190.36.45 counter
 insert rule ip filter INPUT ip saddr 98.138.253.109 counter
 insert rule ip filter INPUT ip saddr 98.139.183.24 counter

After this patch:

 # iptables-translate -I INPUT -s yahoo.com
 nft insert rule ip filter INPUT ip saddr 206.190.36.45 counter
 nft insert rule ip filter INPUT ip saddr 98.138.253.109 counter
 nft insert rule ip filter INPUT ip saddr 98.139.183.24 counter
