File virtinst-set-root-audio-to-none.patch of Package virt-manager

From: Antonio Larrosa <alarrosa@suse.com>
Subject: Disable audio when running virt-manager as root

Running virt-manager as root is not something normally should be done, but since
users are doing it, we better disable audio since pulseaudio isn't running anyway.
See bsc#1222762
