SpdifStreamOut: override getAudioProperties()

This CL restores the behaviour of
PlaybackThread::readOutputParameters_l() that was introduced in
ca5e6143740299c877d69e97f7968cd04476d32c for the SpdifStreamOut path,
but that was changed in 560637e3abc7ff0c28c74f46c39210fa7ad3a354, specifically that format, sample rate and channel mask are assigned from the shim rather than the HAL directly.
