This reverts commit 095fe5b43d.
Pointless renames considered harmful. All they do is force people to
spend extra work updating their configs for no benefit, and hindering
the ability to switch between unstable and stable versions of NixOS.
Like, what was the value of having the "nixos." there? I mean, by
definition anything in a NixOS module has something to do with NixOS...
There was no documentation for the "config" option, and it wasn't quite
clear whether it was supposed to be a file, a string, or what. This
commit removes that ambiguity.
