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