[PATCH 2/7] test: enable VirtIO keyboard

[Ahmad Fatoum <a.fatoum@barebox.org>]

The QEMU ARM64 Virt machine has no input method by default.
As we already had VirtIO input for the web demo, enable it when
--graphic is enabled.

The barebox VirtIO input driver was ported from Linux and both support
only VirtIO v1 devices, so we need to explicitly set
virtio-mmio.force-legacy=false for this to work.
