arptables-nft: Don't print default h-len/h-type values

Default values for --h-len and --h-type being printed for rules where
user didn't provide them is unexpected and confusing. The drawback is
the opposite: If user provided either of them with their default value,
they are later omitted when listing rules. Though since unlike legacy
arptables we can't distinguish between not specified and specified with
default value, we can't fix both - so choose to optimize for the more
likely case.
