perf tools: Add the bash completion for listing subsubcommands of perf help
The bash completion does not support listing subsubcommands for 'perf
help <TAB>', so fix it.
Example:
Before this patch:
$ perf help <TAB>
$
As shown above, the subsubcommands of perf help does not come out.
After this patch:
$ perf help <TAB>
annotate buildid-cache data evlist inject
kvm lock probe report script
test top
bench buildid-list diff help kmem
list mem record sched stat
timechart trace
As shown above, the subsubcommands of perf help can come out now.
