profiles/common: Fix override of sessionVariables.

Ugh... I must have been quite distracted while writing this.

Of course, doing a mkOverride on environment.sessionVariables instead of
environment.sessionVariables.NIX_PATH is going to clear *all*
sessionVariables instead of just replacing NIX_PATH.

This time however, I did a short test with:

nix-instantiate --eval --strict -E '
  (import <nixpkgs/nixos/lib/eval-config.nix> {
    modules = [ ./modules/profiles/common.nix ];
  }).config.environment.sessionVariables
'

... to make sure I just didn't break it *again*.

Also, I'm going to immediately test this after the next evaluation, as
my current system is lacking quite a lot of necessary sessionVariables.
