Title: builder/parallels: Default cdrom0 should be disconnected

This is a minor change and it doesn't break backward compatibility.
Actually, before #1502, we had `cdrom0` device disconnected.

But now (since eb37742ab032c9cd1aa24a2669a220ebab416558) `cdrom0` is not marked as disconnected and the next error message is displayed in GUI:

So, this pull-request fixes that.
