runqemu: support virtio drive type 

Setting QB_DRIVE_TYPE=/dev/vd selects virtio without triggering any
warnings. Previously, that was only possible by setting an unknown
value and relying on the fallback to virtio, which caused some
warnings to be printed.

(From OE-Core rev: 5cbf102662dde6f706a19fa133cfd1e7475eb8c1)
