Subject: virt-install: detect wayland in order to start virt-viewer

When running virt-install using waypipe the DISPLAY variable is not
defined and virt-install will complain that it cannot start virt-viewer.

Check for WAYLAND_DISPLAY as well, DISPLAY is defined only when xwayland
is used. In case of waypipe it configures only WAYLAND_DISPLAY.

Move the check before we check for virt-viewer as without display there
is no point to check if virt-viewer is installed or not.
