tools lib traceevent: Add mono clocks to be parsed in seconds

The mono clocks can display in seconds instead of whole numbers:

trace-cmd-521 [001] 99176715281005: sched_waking: comm=kworker/u16:2 pid=32118 prio=120 target_cpu=002
trace-cmd-521 [001] 99176715286349: sched_wake_idle_without_ipi: cpu=2
trace-cmd-521 [001] 99176715288047: sched_wakeup: kworker/u16:2:32118 [120] success=1 CPU:002
trace-cmd-521 [001] 99176715290022: sched_waking: comm=trace-cmd pid=523 prio=120 target_cpu=000
trace-cmd-521 [001] 99176715292332: sched_wake_idle_without_ipi: cpu=0
trace-cmd-521 [001] 99176715292855: sched_wakeup: trace-cmd:523 [120] success=1 CPU:000

Break it up in seconds:

trace-cmd-521 [001] 99176.715281: sched_waking: comm=kworker/u16:2 pid=32118 prio=120 target_cpu=002

trace-cmd-521 [001] 99176.715290: sched_waking: comm=trace-cmd pid=523 prio=120 target_cpu=000
trace-cmd-521 [001] 99176.715292: sched_wake_idle_without_ipi: cpu=0
trace-cmd-521 [001] 99176.715293: sched_wakeup: trace-cmd:523 [120] success=1 CPU:000
trace-cmd-521 [001] 99176.715301: sched_stat_runtime: comm=trace-cmd pid=521 runtime=80233 [ns] vruntime=66705540554 [ns]
