virtio-fs qualifies as a bootable device minimally under OVMF, but currently the necessary "bootindex" property is missing. Add the property. Expose the property only in the PCI device, for now. There is no boot support for virtiofs on s390x (ccw) for the time being [1] [2], so leave the CCW device unchanged. Add the property to the base device still, because adding the alias to the CCW device later will be easier this way [3].
