ubuntu-drivers: emit latelink=true to /etc/default/ to accept nvidia eula

To accept NVIDIA EULA, cloud-init needs to emit latelink=true to the shell
config file /etc/default/linux-modules-nvidia prior to installing NVIDIA
drivers with the ubuntu-drivers command. This will allow NVIDIA modules
prior to installing drivers enabled for linking to the running kernel.

Overall LGTM; the one question I think we _need_ to answer is on diff-line 20. The other comment is a nice-to-have.
