src/ct: provide fixed data lengh sizes for ip/ip6 keys

nft can load but not list this:

table inet filter {
 chain input {
  ct original ip daddr {1.2.3.4} accept
 }
}

Problem is that the ct template length is 0, so we believe the right hand
side is a concatenation because left->len < set->key->len is true.
nft then calls abort() during concatenation parsing.
