perf stat: Add before_metric argument

Browse source

Unfortunately, event running time, percentage and noise data are printed
in different positions in normal output than CSV/JSON.  I think it's
better to put such details in where it actually prints.

So add before_metric argument to print_noise() and print_running() and
call them twice before and after the metric.
