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
...
