perf stat: Make all displayed event names parseable as well

Right now we display this by default:

          0.202204 task-clock-msecs         #      0.282 CPUs
                 0 context-switches         #      0.000 M/sec
                 0 CPU-migrations           #      0.000 M/sec
                85 page-faults              #      0.420 M/sec

The task-clock-msecs event cannot actually be passed back as an
event name, the event name we recognize is 'task-clock'.

So change the output of the cpu-clock and task-clock events
to be idempotent.

( Units should be printed out in the right-side column, if needed. )
