linux: Update to 3.2.37
Add psutil pythonPackage
Remove unfree ATI drivers package from the channel

Urghhhhh...
Remove some oversized packages from the channel

E.g. urbanterror takes up 2x720 MiB.
Pass ‘config’ to stdenv/generic/default.nix

This is a backport of cf8daf63120adedbeaf5bc8c2f396be2496a741e in
stdenv-updates (sans the userHook stuff).
Add config option ‘allowUnfree’

If set to false, mkDerivation will throw an exception if a package has
an unfree license.  ‘release-lib.nix’ uses this to enforce that we
don't build unfree packages as part of the Nixpkgs channel.  Since
this is set through Nixpkgs' ‘config’ argument, it's more finegrained
than $HYDRA_DISALLOW_UNFREE.
