Arian van Putten 5276ebb5ee nixos: Get rid of systemConfig kernel parameter
It was introduced in c10fe14 but removed in c4f910f.

It remained such that people with older generations in their boot
entries could still boot those. Given that the parameter hasn't had any
use in quite some years, it seems safe to remove now.

Fixes #60184
