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%]
1,282,201 branches # 0.053 M/sec [99.84%]
24126.221811 cpu-clock [99.62%]
24121.689540 task-clock # 24.098 CPUs utilized [99.52%]
1.001001017 seconds time elapsed
This patch fixes this:
Performance counter stats for 'sleep 1':
13,540,843 instructions # 0.00 insns per cycle
180 faults # 0.007 K/sec [99.94%]
2,875,386 branches # 0.119 M/sec [99.82%]
24144.221137 cpu-clock [99.61%]
24133.515366 task-clock # 24.109 CPUs utilized [99.52%]
