    data: Fix wayland disabling on hybrid nvidia machines
    
    commit 9ecf839913846211ffe10e1243a360c3cb66ff61 was supposed
    to make sure vendor nvidia users on hybrid systems kept getting
    Xorg by default.
    
    Unfortunately, I misunderstood the scope of environment changes,
    and so the rules don't work as designed.
    
    This commit drops the use of environment and instead just checks
    for /sys/module/nvidia_drm directly.
