Add tests to exercise packet path for rbtree and hash set types.
We check both positive (added address is matched) and negative
matches (set doesn't indicate match for deleted address).
For ranges, also validate that addresses preceeding or trailing
a range do not match.
Pipapo has no test to avoid duplicating what is already in
kernel kselftest (nft_concat_range.sh).
