Add rootwrap filter rule for radvd-kill script
In patch [1] support for custom kill scripts was added.
We also added rootwrap filter rules for such scripts to
kill dnsmasq, haproxy, dibbler and keepalived processes.
But we missed to add rule for radvd-kill so this patch
adds it (better late than never ;))

Title:
Missing rootwrap filter rule for radvd kill script
Status in neutron:
Fix Released
Bug description:
In commit https://opendev.org/openstack/neutron/commit/93015527f02cb54b0b2bc07c8c9c239c63878264 we added support for custom kill scripts and we added rootwrap filter rules for scripts to kill dnsmasq, haproxy, keepalived but we missed same rule for radvd.
Now if such radvd-kill script is used, it fails in Neutron-L3-agent with error like:
2020-04-13 11:07:43.064 31530 ERROR neutron.agent.linux.utils [-] Rootwrap error running command: ['radvd-kill', '9', '43476']: multiprocessing.managers.RemoteError:
