[nft PATCH] nft: don't resolve hostnames by default

[Arturo Borrero Gonzalez]

This patch changes the behaviour of nft to don't translate IP
addresses to hostnames when printing rules.

So, the behaviour of '-n' ends like this:
 <no -n given>		show IP addresses numerically
 -n			translate IP addresses to names
 -nn			show Internet services and uid/gid numerically
 -nnn			show protocols numerically
