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.
