Provide an encoding agnostic version of compare_stream

The FileUtils implementation in Ruby 2.0+ was modified in a manner where it cannot properly compare File and StringIO instances. To sidestep that issue this method reimplements the faster 2.0 version that will correctly compare binary File and StringIO streams.
