Subject: [PATCHv2 net] selftests: netfilter: Pass the family parameter to conntrack tool

From: yiche <yiche@...hat.com>

Fixes: 619ae8e0697a6 ("selftests: netfilter: add test case for conntrack helper assignment")

Fix nft_conntrack_helper.sh fake fail:
conntrack tool need "-f ipv6" parameter to show out ipv6 traffic items.
sleep 1 second after background nc send packet, to make sure check
is after this statement executed.
