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.

   # File lib/puppet/file_system/posix.rb
13 def compare_stream(path, stream)
14   open(path, 0, 'rb') do |this|
15     bsize = stream_blksize(this, stream)
16     sa = String.new.force_encoding('ASCII-8BIT')
17     sb = String.new.force_encoding('ASCII-8BIT')
18     loop do
19       this.read(bsize, sa)
20       stream.read(bsize, sb)
21       return true if sa.empty? && sb.empty?
22       break if sa != sb
23     end
24     false
