um: virtio_uml: Disallow modular build
This driver *can* be a module, but then its parameters (socket path) are untrusted data from inside the VM, and that isn't allowed. Allow the code to only be built-in to avoid that.

+ * This driver allows virtio devices to be used over a vhost-user socket.

* Guest devices can be instantiated by kernel module or command line

*
- * [virtio_uml.]device=<socket>:<virtio_id>[:<platform_id>]
+ * virtio_uml.device=<socket>:<virtio_id>[:<platform_id>]
* where:
* <socket> := vhost-user socket path to connect
* <virtio_id> := virtio device id (as in virtio_ids.h)
