Daniel P. Berrangé e88367095f qemu: populate <audio> element with default config
Currently the QEMU driver secretly sets the QEMU_AUDIO_DRV env variable

 - VNC - set to "none", unless passthrough of host env variable is set
 - SPICE - always set to "spice"
 - SDL - always passthrough host env
 - No graphics - set to "none", unless passthrough of host env variable is set

The setting of the QEMU_AUDIO_DRV env variable is done in the code which
configures graphics.

If no <audio> element is present, we now auto-populate <audio> elements
to reflect this historical default config. This avoids need to set audio
env when processing graphics.
