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.

def compare_stream(path, stream)
  open(path, 0, 'rb') do |this|
    bsize = stream_blksize(this, stream)
    sa = "".force_encoding('ASCII-8BIT')
    sb = "".force_encoding('ASCII-8BIT')
    begin
      this.read(bsize, sa)
      stream.read(bsize, sb)
      return true if sa.empty? && sb.empty?
    end while sa == sb
    false
