fix

With nvidia-driver-390 (or older) or nvidia-secondary-driver-390,
`nvidia-xconfig --enable-all-gpus` fails with:
> WARNING: error retrieving symbol nvCfgIsPrimaryDevice from libnvidia-cfg.so.1:
>         Undefined symbol "nvCfgIsPrimaryDevice"
> ERROR: Unable to determine number of GPUs in system; cannot honor
>       '--enable-all-gpus' option.

nvidia-xconfig is required for functionality of nvidia-hybrid-graphics-390 for
legacy Nvidia Optimus GPUs.

The library incompatibility occurs since libnvidia-cfg.so.1 is part of nvidia
driver port, not the xconfig port.

Ideally nvidia-xconfig version should always match driver version, but the
existing ports do not accomplish this.
Using nvidia-xconfig 390.151 for drivers 390 and earlier, and nvidia-xconfig
470.86 for drivers 470 and newer seems sufficient.
