perf stat: Add units to nanosec-based counters
Ingo pointed out that the task-clock counter should have the units explicitly stated since it is not a counter. Before: perf stat -a -- sleep 1 Performance counter stats for 'sleep 1': 16186.874834 task-clock # 16.154 CPUs utilized ... After: perf stat -a -- sleep 1 Performance counter stats for 'system wide': 16146.402138 task-clock (msec) # 16.125 CPUs utilized ...
