build_rootfs.sh: Switch away from cloud kernel

The cloud kernel is just a subset of the full Debian kernel with some
drivers removed, but on a physical server we need some of those drivers,
so rather than have two configs, let's just use the full kernel.

The NVIDIA driver is bumped again because of a compilation issue with
the Linux 6.0 kernel currently in bullseye backports.
