mediaserver and drmserver both have permission to read oemfs related files. However, there are no search permissions on the directory, so the files would be unreachable. Grant search permissions on the oemfs directory, so that the files within that directory can be read. Bug: 17954291 Change-Id: I9e36dc7b940bd46774753c1fa07b0f47c36ff0db
