test: dm: virtio: Split out virtio device tests
Virtio tests that find a child device require the virtio device driver
to be included in the build so it can probe. The sandbox virtio
transport driver currently reports a virtio-blk device so make sure the
corresponding driver is built before running tests that need it.
