netfilter: ctnetlink: dump conntrack ID in event messages

Browse source 
Conntrack ID is not put (anymore ?) in event messages. This causes
current ulogd2 code to fail because it uses the ID to build a hash in
userspace. This hash is used to be able to output the starting time of
a connection.

Conntrack ID can be used in userspace application to maintain an easy
match between kernel connections list and userspace one. It may worth
to add it if there is no performance related issue.

[ Patrick: it was never included in events, but really should be ]
