Drop recurseIntoAttrs from python33Packages and pypyPackages.

We cannot import the packages from all of these three packages sets into
the global namespace, because they are indistinguishable. For example:

  $ nix-env -qaP \* | grep pylint
  pypyPackages.pylint                 pylint-0.26.0
  python33Packages.pylint             pylint-0.26.0
  python27Packages.pylint             pylint-0.26.0

When someone tries to install pylint by running "nix-env -i pylint",
then it's impossible to tell which one of these three versions was
chosen.

I can think of two ways to remedy this problem with recurseIntoAttrs:

 1) Bake the name of the Python interpreter into every package's name,
    i.e. offer "python27-pylint", "python33-pylint", and so on.

 2) Ensure that all non-default package sets mark all their packages
    'lowPrio' to unsure that the choice during installation is
    deterministic.

Move namePrefix="" python packages out of python-packges.nix

It doesn't make sense to build tools/applications with three different
python interpreter versions, so move them out of python modules list.
