Enable config requirements for IDM ivshmem + virtio-vsock transport

For KVM, we currently have a prototype IDM implementation running over
virtio-console. Due to performance issues, we might replace it with an
implementation based on ivshmem + virtio-vsock.

Enable the kernel options that have been found to be necessary for this
implementation.
