Update nvidia-glx-driver to 470.82.00
Changes:
- Fixed a bug that can cause a kernel crash in SLI Mosaic configurations
- Added support for the EGL_NV_robustness_video_memory_purge
Packager's note: According to the response I received on the Nvidia Developer Forum this should also fix the black screen on boot for G-Sync monitors. Also fixed the json file locations according to @ReillyBrogan's suggestions as with nvidia-beta-driver
