perf tools: Fix the bash completion for listing subcommands of perf
The bash completion does not support listing subcommands for 'perf --<long option> <TAB>'. Example: Before this patch: $ perf --debug <TAB> $ As shown above, the subcommands of perf does not come out. After this patch: $ perf --debug <TAB> annotate buildid-cache data evlist inject kvm lock probe report script test top version bench buildid-list diff help kmem list mem record sched stat timechart trace As shown above, the subcommands of perf can come out now.
