perf tools: Fix the bash completion to support listing events for --event
The bash completion only supports -e rather than --event, so fix it.
Example:
Before this patch:
$ perf record --event <TAB>
$
As shown above, the events of record does not come out.
After this patch:
$ perf record --event <TAB>

As shown above, the events of record can come out now.
