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
