Subject: [PATCH] perf tools: Add the bash completion for listing
 subsubcommands of perf trace

The bash completion does not support listing subsubcommands for 'perf
trace <TAB>', so fix it.

Example:

Before this patch:

 $ perf trace <TAB>
 $

As shown above, the subsubcommands of perf trace does not come out.

After this patch:

 $ perf trace <TAB>
 record

As shown above, the subsubcommands of perf trace can come out now.
