[libvirt PATCH 04/25] vircgroupv2: properly detect empty tasks

[Pavel Hrdina]

With cgroups v2 the file cgroup.procs will never be empty if threading
is enabled as it will always have ID of all processes even if all
threads of the processes are moved to sub-cgroups. If that happens the
file cgroup.threads will be empty.
