services: nvidia: Only invoke commands when NVIDIA driver is in use.
* nongnu/services/nvidia.scm (nvidia-service-type): Don't extend
kernel-module-loader-service-type, move this part to…
(nvidia-shepherd-service)[start]: …here.
Check driver and command availablity.
[stop]: Likewise.
[modules]: Add (guix build utils) for ‘invoke/quiet’.
Add (rnrs io ports) for ‘get-line’.
