perf report: Fix stdio event name header printing
In the past we tried to avoid printing the name of the event when just one event was found in the perf.data file, after some refactorings it ended up not printing the event name if just one hist_entry was found in one of the events. Fix it by always printing the name of the event, even if just one is found.
