cgroup: Remove steal time from usage_usec
The CPU usage time is the time when user, system or both are using the CPU.
Steal time is the time when CPU is waiting to be run by the Hypervisor. It
should not be added to the CPU usage time, hence removing it from the
usage_usec entry.
Fixes: 936f2a70f2077 ("cgroup: add cpu.stat file to root cgroup")
