pid namespaces: allow signalling cgroup-init
Only the global-init process must be special - any other cgroup-init
process must be killable to prevent run-away processes in the system.
TODO: Ideally we should allow killing the cgroup-init only from parent
cgroup and prevent it being killed from within the cgroup.
But that is a more complex change and will be addressed by a follow-on
patch. For now allow the cgroup-init to be terminated by any process
with sufficient privileges.
