Title: Use universal_newlines for Python 3 compatibility.

The call to subprocess.Popen in get_cask_path returns a byte string
from the subprocess, which is not valid as a value in os.environ.
Passing universal_newlines=True sets the encoding of the process
to the user's default locale, which should do the right thing.
