perf annotate: Display all available events on --stdio

When we perform the following command lines:

  $ perf record -e "{cycles,branches}" ./div
  $ perf annotate main --stdio

The output shows only the first event, "cycles" and the displaying
format is not correct.

                   :            }

The issue is that the value of the 'nr_percent' variable is hardcoded to
1.  This patch fixes it.

With this patch, the output is:
