perf, tools: Support long descriptions with perf list -v

Previously we were dropping the useful longer descriptions that some
events have in the event list completely. This patch makes them appear with
perf list.

Old perf list:

baclears:
  baclears.all
       [Counts the number of baclears]

vs new:

perf list -v:
...
baclears:
  baclears.all
       [The BACLEARS event counts the number of times the front end is resteered, mainly when
        the Branch Prediction Unit cannot provide a correct prediction and this is corrected
        by the Branch Address Calculator at the front end. The BACLEARS.ANY event counts the
        number of baclears for any type of branch]
