Title: Delegate external encoding

Not sure if this was something that was added in a new version of
minitest but I was getting this error when running tests:

```
/Users/tony/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/minitest-5.4.3/lib/minitest.rb:572:in `aggregated_results': undefined method `external_encoding' for # (NoMethodError)

```

Looking at minitest source it seemed like it wanted to send that message to io so I just delegated it over and things work now.
