Rework the kernel configuration fragment application to prune out
a bunch of the configuration for physical hardware for the
virtio-aarch64 kernel. As well, add a virtio guest kernel specific
fragment to enable a PCI CAN device driver that works with QEMU's
emulation. That will provide a fallback until something can be
worked out with respect to virtio-can.
