tools/power turbostat: Enable non-privileged users to read sysfs counters
A group of counters called "sysfs" displays software
C-state request counts and resulting perceived C-state residency.
They are not built-in counters that turbostat knows about ahead of time,
rather they are discovered in sysfs when turbostat starts.
Thus, they are added dynamically, using the same interface
as user-added MSR counters.
When turbostat enters "no-msr" mode, such as when running as a
non-privileged user, it clears all added counters.
Updating that to clear only actual MSR added counters
allows regular users to see the sysfs counters.
