[PATCH 4/4] dmband: Use the generic IPersistStream implementation from dmobject

IPersistStream here fulfills the exact same role as the one from
DirectMusicObject. So use the generic implementation at the cost of
wasting sizeof(void*) bytes in the COM object for the unused
IDirectMusicObject_iface struct field.
