perf tools: Fix the bash completion for listing subsubcommands of perf subcommand
The bash completion does not support listing subsubcommands for 'perf
kvm|kmem|mem|lock|sched --<long option> <TAB>', where 'kvm|kmem|mem|
lock|sched' are all subcommands of perf.
Example:
Before this patch:
$ perf kvm --verbose <TAB>
$
As shown above, the subsubcommands of perf kvm does not come out.
After this patch:
$ perf kvm --verbose <TAB>
buildid-list diff record report stat
top
As shown above, the subsubcommands of perf kvm can come out now.
