perf script: Add -e option to flamegraph script

When processing the perf data file generated with multiple events,
the flamegraph script will count all the events regardless of
different event names.

This patch tries to add a -e option to specify the event name that
the flamegraph will be generated accordingly. If the -e option omitted,
the behavior remains unchanged.
