service/audren_u: Report proper device names

Browse Source 
AudioDevice and AudioInterface aren't valid device names on the Switch.
We should also be returning consistent names in
GetActiveAudioDeviceName().

While we're at it, we can also handle proper name output in
ListAudioDeviceName, by returning all the available devices on the
Switch.
