[libvirt] [PATCH 5/9] qemu_cgroup: put qemu right into emulator sub-cgroup
Move qemuSetupCgroupForEmulator up under qemuSetupCgroup. That way
we move the one main thread right into the emulator cgroup, instead
of moving multiple threads later on. And we do not actually want any
threads running in the parent cgroups (cpu cpuacct cpuset).
