Subject: [PATCH] Fix qemu config for multi-head gpu

The old config would create two separate VGA compatible graphics
adapters. Redox currently only supports this when the firmware
initializes both graphics adapters as boot framebuffers. Only UEFI
supports this however. Using a single multi-head virtio-gpu graphics
adapter makes it work on BIOS too.
