pidns: Add setns support
- Pid namespaces are designed to be inescapable so verify that the
passed in pid namespace is a child of the currently active
pid namespace or the currently active pid namespace itself.
Allowing the currently active pid namespace is important so
the effects of an earlier setns can be cancelled.
