Title: [GH-1977] revert and alternate fix

@mitchellh, the internal encoding doesn't seem to work. Therefore,
I reverted that previous change to vagrant.rb.

However, I found two alternate solutions. Either transcoding,
`/etc/redhat-release` to ISO-8859-1 on open, or using something
like File.binread to transcode the file contents to raw.
