Avoid to print the reject with value in the translation when the value
is the default.
Before this patch:
$ sudo ip6tables-translate -A FORWARD -p TCP --dport 22 -j REJECT
nft add rule ip6 filter FORWARD tcp dport 22 counter reject with icmpv6 type port-unreachable
After this patch:
$ sudo ip6tables-translate -A FORWARD -p TCP --dport 22 -j REJECT
nft add rule ip6 filter FORWARD tcp dport 22 counter reject

v2:
- Remove default constant, as Pablo suggested.
