    I.e. support tracing just tracepoints, without strace like
    raw_syscalls:*.
    
    [acme@ssdandy linux]$ trace --no-sys --ev sched:*exec,sched:*switch,sched:*exit usleep 1
      0.048 (     ): sched:sched_process_exec:filename=/usr/bin/usleep pid=27298 old_pid=27298)
      0.369 (     ): sched:sched_switch:usleep:27298 [120] S ==> swapper/5:0 [120])
      0.452 (     ): sched:sched_process_exit:comm=usleep pid=27298 prio=120)
    [acme@ssdandy linux]$
    
    TODO: remove that (...) thing when --no-syscalls is specified.
