* benchmark/driver.rb: some refactoring.

Browse source 
(1) Remove `average differential'.
  In this benchmark driver, We should not care about `average'.
  We use fastest score because this score should not include
  any disturbances (affections of background process, etc).
  If you care about timing affect, I recommend `median'
  score with more than 5 examinations rather than simple
  `average' score (`average' score was affected by error scores).
  (2) Show log file name.
  (3) Change default directory from './' to driver's directory.
