x11-drivers/nvidia-drivers: workaround 0/495 dbus powerd spam

Not ideal and may possibly have other impacts, but it seem
better than leaving this issue alone as it can be doing ~10000
requests per second depending on what's being ran.

Alternative known workaround to at least prevent logging issues
(dbus black hole) would require user interaction and doesn't
seem worth it here.
