radvd kill-script is always enabled, actually killing neutron l3 agent

[Bernard Cafarelli]

After patch https://opendev.org/openstack/tripleo-heat-templates/commit/2dc7066b050ecf22dc9e5909061272ffe765ebfc there are "kill scripts" for all processes managed by e.g. L3 agent, even for radvd which isn't run in sidecar container but in neutron-l3-agent container directly (by default).
That is causing various issues.
First one was in Neutron, and is covered by https://bugs.launchpad.net/neutron/+bug/1873240 actually allowing the kill script execution
But with fix in https://review.opendev.org/#/c/720431/ we hit another issue. As radvd-kill script is now allowed to be executed by neutron-l3-agent, it finds neutron-l3-agent container and kills it.
So every time when radvd is killed by neutron-l3-agent because e.g. IPv6 subnet is deleted from router, agent is also restarted (killed by radvd-kill script and started back by systemd).
