tracing: finetune branch-tracer output

Steve suggested the to change the output from this:

>  bash-3471  [003]   357.014755: [ MISS ] sched_info_dequeued:sched_stats.h:177
>  bash-3471  [003]   357.014756: [ .... ] update_curr:sched_fair.c:489
>  bash-3471  [003]   357.014758: [ .... ] calc_delta_fair:sched_fair.c:411

to this:

>  bash-3471  [003]   357.014755: [ MISS ] sched_info_dequeued:sched_stats.h:177
>  bash-3471  [003]   357.014756: [  ok  ] update_curr:sched_fair.c:489
>  bash-3471  [003]   357.014758: [  ok  ] calc_delta_fair:sched_fair.c:411

as it makes it clearer to the user what it means exactly.
