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] 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] 99176.715288: sched_wakeup:         kworker/u16:2:32118 [120] success=1 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]
