[libvirt] [PATCH 1/7] qemuProcessStartPRDaemonHook: Try to set NS iff domain was started with one
Users have possibility to disable qemu namespace feature (e.g.
because they are running on *BSD which lacks Linux NS support).
If that's the case we should not try to move qemu-pr-helper into
the same namespace as qemu is in.
