Manual: add info about QEMU_AUDIO_DRV

hramrach on IRC had an issue with audio not working. He was using
suse and his qemu defaulted to using the pulseaudio audio driver instead
of spice.  Explicitly setting the audio driver to spice using the
QEMU_AUDIO_DRV environment variable solved the problem. Add this tip to
the manual for others having the same issue in the future.

The `-soundhw hda` option provides an audio device for the guest to use for
audio playback and recording. In order for spice audio to work properly, qemu
must use the 'spice' audio driver. Depending on how qemu was built, however,
this might not be the default audio driver. To ensure qemu uses the spice audio
driver, you can set the environment variable `QEMU_AUDIO_DRV=spice`.
