benchmark: drop legacy benchmark drivers
It seems like they are all benchmark drivers but "benchmark/driver.rb" is the latest and others are no longer used.
It's confusing to have multiple drivers (and actually I used benchmark/run.rb since I didn't know I should use benchmark/driver.rb).
As I'm going to support only benchmark/driver.rb features in Misc#14902, let me delete them.
