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