bridge_softmix: Use MSID:LABEL metadata as the cloned stream's appendix

Browse Source 
To avoid the stream name collide if there're more than one video track
in one client. If client has multi video tracks, the name of ast_stream
which represents each video track may be the same. Use the MSID:LABEL
here because it's identifiable.
