bootstd: Correct virtio block-device handling
At present virtio tries to attach QEMU services to a bootdev device, which
cannot work. Add a check for this.
Also use bootdev_setup_sibling_blk() to create the bootdev device, since
it allows the correct name to be used and bootdev_get_sibling_blk() to
work as expected.
The bootdev is not created on sandbox since it does have a real virtio
device and it is not possible to read blocks.
