[PATCH v4 2/3] trace-cmd: Add a define to enable per CPU timestamps synchronization

["Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>]

The new define TSYNC_PER_CPU, enabled by default, can be used to enable
the per CPU timestamps synchronization. It is mostly for development purposes,
to compare this new logic to the legacy one, where a single CPU is used.
