audio policy: allow USB device for voice comm capture in speakerphone 

When no built-in microphone is present, allow capture from USB accessory
(e.g web cam) for voice communication use cases even when speakerphone
mode is on. Even if the echo cancelling does not perform well, this is
better than a failure to capture.
