dev-php/sebastian-diff: new revision to fix autoloader class names.

Two of the class names in this package's autoload.php were in error:
they were named after the filename, instead of the classes that they
actually contain (perhaps this is a bug upstream?). In any case, the
PHPUnit test suite for symfony-finder was failing looking for a class
that it couldn't find. The new revision should force users to install
the updated autoload.php.
