sched/stat: make cpu.proc.stat file also available in cgroup-v2
We use the fact that cpuacct controller is implicitly enabled in
cgroupv-2 by previous patch. So we can just do everyting the same as we
do it on cgroup-v1 where we have both cpu and cpuacct controllers
mounted together.
Note: Stats in cpu.proc.stat give per-cpu per-cgroup usages which are
used in vcmmd to calculate per-numa cpu loads for it's balancing
algorithm. This used both for Containers and VMs.
