tracing: branch tracer, tweak output

Browse Source 
Impact: modify the tracer output, to make it a bit easier to read

Change the output from:

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

to:

>  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

it's good to have fields aligned vertically, and the only important
information is a prediction miss, so display only that information.
