nixos/frigate: allow configuring a libva driver 

In my testing this helped steer VA-API towards the correct card and also
made it show GPU statistics in performance monitoring.

        Force usage of a particular VA-API driver for video acceleration. Use together with `settings.ffmpeg.hwaccel_args`.



        Setting this *is not required* for VA-API to work, but it can help steer VA-API towards the correct card if you have multiple.



        :::{.note}

        For VA-API to work you must enable {option}`hardware.graphics.enable` (sufficient for AMDGPU) and pass for example

        `pkgs.intel-media-driver` (required for Intel 5th Gen. and newer) into {option}`hardware.graphics.extraPackages`.
