host/start-vm: support multiple block devices
This is the first step to being able to do things like having a static base image for an application VM, and another image containing the application to run. When we actually use multiple images we'll need to change how we boot so we know the kernel is booting from the right image — probably by PARTUUID or PARTLABEL — because we can't guarantee how the kernel orders disks inside the VM.
