perf tools: Add the bash completion for listing subsubcommands of perf timechart
The bash completion does not support listing subsubcommands for 'perf
timechart <TAB>', so fix it.
Example:
Before this patch:
$ perf timechart <TAB>
$
As shown above, the subsubcommands of perf timechart does not come out.
After this patch:
$ perf timechart <TAB>
record
As shown above, the subsubcommands of perf timechart can come out now.
