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.
