sys_stats: add tracking of cycles stolen by host for executing something else than the guest (#1141)

When tracing a guest OS, it is hard to deduce how much time was taken by
guest n actually running in the absence of knowing cycles stolen by host
to execute something else that this guest. Add logging for this from
/proc/stat so that this can be sampled and shown in perfetto UI.
