Subject: [PATCH 3/3] kio_file: pass the absolute path to
 QMimeDatabase::mimeTypeForFile()

Otherwise detecting the mime type based on the file content may fail and
return application/octet-stream.

And pass the whole url to createUDSEntry(), less QFile::decodeName/encodeName()
in the middle is better and less error prone.

Note that without this change a MimeTypeFinderJob could end up failing to
find the mime type of a local file based on the file contents.

(cherry picked from commit c748d6987252fafc296cde9351b289ef734cf861)
