perf tools: fix event parsing of comma-separated tracepoint events

There are number of issues that prevent the use of multiple tracepoint events
being specified in a -e/--event switch, separated by commas.

For example, perf stat -e irq:irq_handler_entry,irq:irq_handler_exit ...  fails
because the tracepoint event parsing code doesn't recognize the comma separator
properly.

This patch corrects those issues.
