The daemon started by the test-integration script needs to run without
firewalld integration to make sure that daemons started by networking
tests will handle firewalld reload without any interference (i.e.
without another daemon racing against them to recreate the iptables
chains).
Most tests are already running their own daemons, but the few that don't
and need firewalld integration are updated to start their own.
