Enable universal newline when reading scss files

SCSS-Lint seems to choke on a file that uses windows-style newlines with
carriage returns. (To type a windows-style newline with carriage return
in Vim, press <Ctrl>+v<Ctrl>+m in insert mode. This will show up as ^M.)

To avoid this, we can encode the file contents using String#encode's
:universal_newline option, which

> Replaces CRLF (“rn”) and CR (“r”) with LF (“n”) if value is true.

I thought that maybe we wouldn't need the force_encoding anymore after
this change, but that was not the case since the test that was added
with that change started failing once I removed the force_encoding.

Fixes #700.
