Store the clock offset table inside the trace
...
The ovnisync tool now generates it by default inside ovni directory,
and the emulator recognizes it by default if exists.

These events only show if a thread has been removed from the CPU, but
doesn't provide information about what other thread caused the context
switch. This type of information can be obtained even with strict
/proc/sys/kernel/perf_event_paranoid settings.
