[PATCH 7/7] audio, qtest: get rid of QEMU_AUDIO_DRV

[Paolo Bonzini <pbonzini@redhat.com>]

Default audio devices can now be created with "-audio".  Tests for
soundcards were already using "-audiodev" if they want to specify a
particular backend, for the others remove the last remnants of
legacy audio configuration.
