Pre-install vulkan-virtio

Prajna Sariputrarequested to merge
psariputra/kde-linux:patch-1 into master

This driver (also called Venus in some places) enables hardware accelerated Vulkan in virtual machines that support it (in particular QEMU 9.2 or newer paired with virglrenderer 1.0.0 or newer) if KDE Linux is used as a guest in such a VM.

Typically hardware accelerated graphics in QEMU VMs is handled by the virgl driver, however starting with Mesa 26.1 it is considered unmaintained, and may get removed in the future, so including Venus would help ensure that KDE Linux is prepared for that future.

Unfortunately libvirt (and therefore all GUI virtual machine apps based on it, like virt-manager for example) still doesn't expose settings for Venus so the configuration file has to be edited manually or QEMU has to be invoked manually to test this properly, see https://gitlab.com/libvirt/libvirt/-/work_items/638 for more details on that.
