tools/power turbostat: Handle non-root legacy-uncore sysfs permissions
/sys/devices/system/cpu/intel_uncore_frequency/package_X_die_Y/
may be readable by all, but
/sys/devices/system/cpu/intel_uncore_frequency/package_X_die_Y/current_freq_khz
may be readable only by root.
Non-root turbostat users see complaints in this scenario.
Fail probe of the interface if we can't read current_freq_khz.
