> perf stat: Revert checks for duration_time
>
> This reverts e864c5ca145e ("perf stat: Hide internal duration_time
> counter") but doing it manually since the code has now moved to a
> different file.
>
> The next patch will properly implement duration_time as a full event, so
> no need to hide it anymore.
