gdm.rules: Keep wayland enabled in all nvidia configurations allowing it
Nvidia drivers since version 470 supports both native wayland and
accelerated Xwayland. The latter also works in hybrid configurations
using nvidia Optimus (the session will run using the main integrated
GPU, but it will be possible to use switcherooctl to run applications
using the discrete nvidia card).
However, the gdm rules were including a line that was supposed to
disable such scenario, but it didn't actually work as expected, so we
can safely remove it, without changing the behavior.
At the same time we can tune the rules so that, when the nvidia-drm
module is loaded, if the driver version is minor than 470, wayland is
disabled.
