sound: request char-major-* module aliases for missing OSS devices
Till now missing OSS devices emitted sound-slot/service-* module alises instead of the standard char-major-* if a missing device number is opened if soundcore is loaded. The custom module aliases don't have any inherent benefit than backward compatibility. sound-slot/service-* module aliases is scheduled to be removed and to help the transition this patch makes soundcore emit the standard module alises along with the custom ones.
