    runqemu: add virtio block device
    
    Implement new QB_DRIVE_TYPE="/dev/vdb" which falls back
    to virtio block device emulated by qemu.
    That is needed to support following qemu command line:
    -drive id=disk0,file=%s,if=none,format=%s \
      -device virtio-blk-device,drive=disk0'
    
    Real use case is arm64 emulation with qemu with atf+optee+uboot,
    so that uboot driver sees this disk and able to load from it.
