perf stat: Rework header display

Browse source

There are print_header() and print_interval() to print header lines before
actual counter values.  Also print_metric_headers() needs to be called for
the metric-only case.

Let's move all these logics to a single place including num_print_iv to
refresh the headers for interval mode.
