Subject: [PATCH ghau51/ghau40 v7 09/12] contid: interpret correctly CONTAINER_ID contid field csv

The CONTAINER_ID record contid field can contain comma-separated values
when accompanying a NETFILTER_PKT record.  Records appeared interpreted
as such:

Wrong:
	CONTAINER_ID msg=audit(2019-04-10 13:20:18.746:1690) : contid=777 666,333
Right:
	CONTAINER_ID msg=audit(2019-04-10 13:20:18.746:1690) : contid=777,666,333
