tools/power/turbostat: Move process to root cgroup
When available CPUs are reduced via cgroup cpuset controller, turbostat
will exit with errors (For example):
get_counters: Could not migrate to CPU 0
turbostat: re-initialized with num_cpus 20
get_counters: Could not migrate to CPU 0
turbostat: re-initialized with num_cpus 20
Move the turbostat to root cgroup, which has every CPU.
Writing the value 0 to a cgroup.procs file causes the writing
process to be moved to the corresponding cgroup.
