Backend: prefer debug_msg over PBD::Transmitter in threads 

PBD::Transmitter is neither thread-safe nor rt-safe. This likely
fixes a crash on macOS when process-threads are started.
Many threads simultaneously enter coreaudio_process_thread() and
log a message calling `PBD::info << .. << endmsg` simultaneously.
