perf top: Save and display the drop count stats
Add drop count to 'perf top' headers:
# perf top --stdio
PerfTop: 3549 irqs/sec kernel:51.8% exact: 100.0% lost: 0/0 drop: 0/0 [4000Hz cycles:ppp], (all, 8 CPUs)
# perf top
Samples: 0 of event 'cycles:ppp', 4000 Hz, Event count (approx.): 0 lost: 0/0 drop: 0/0
The format is: <current period drop>/<total drop>
