perf tools: Fix the bash completion for listing events of perf subcommand record|stat|top -e
The bash completion does not support listing events for 'perf kvm|kmem|
mem|lock|sched record|stat|top -e <TAB>', where 'kvm|kmem|mem|lock|sched'
are all subcommands of perf.
Example:
Before this patch:
$ perf kvm record -e <TAB>
$
As shown above, the events of record does not come out.
After this patch:
$ perf kvm record -e <TAB>

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