perf stat: Align scaled output of cpu-clock

The output of cpu-clock event is controlled in nsec_printout(),
but its alignment was broken:

 Performance counter stats for 'sleep 1':

         6,038,774 instructions              #    0.00  insns per cycle
               180 faults                    #    0.007 K/sec                   [99.95%]

This patch fixes this:

 Performance counter stats for 'sleep 1':

        13,540,843 instructions              #    0.00  insns per cycle
