pythonPackages.Theano: move and rename variants

We have two derivations, one that supports Cuda, and one that does not.
The names, TheanoWithCuda and TheanoWithoutCuda, now reflect that.
Furthermore, a boolean passthru.cudaSupport was added.

In the future the two derivations should be merged in one, with a
parameter `cudaSupport`.
