    Update util.php

    Fix CURLOPT_FOLLOWLOCATION bug with open_basedir or safe_mode restriction enabled.

When detecting whether the file to be downloaded is on external storage,
the correct path needs to be used.

It turns out that \OC\Files\View is needed to resolve the path correctly
relative to the user's home.

That method was moved to the external storage recently so
isn't needed here any more.
