add non-qubes-audio to kicksecure-xfce

(This results in installation of libasound2, alsa-utils, pulseaudio
and pavucontrol in Kicksecure XFCE since these are the current dependencies
of non-qubes-audio. This also install these packages on Whonix Host since
Whonix Host (whonix-host-xfce-kvm-freedom) currently depends on
kicksecure-xfce.)
