nixos/qemu-vm: Ensure 9pnet_virtio module is loaded for shared dirs

Browse Source 
When `diskImage = null`, the root fs is a tmpfs instead of
`/dev/vda`. Thus, it doesn't have to wait for virtio modules to load
before being mounted. The root fs is a dependency of shared
directories by nature of being their parent directory. Without
depending on `/dev/vda`, these shared directories may attempt to mount
without virtio modules being loaded.
