Update the model list to those models that are compatibly with the
latest spaCy version:
https://github.com/explosion/spacy-models/blob/master/compatibility.json
The updated model file evaluates to the following packages:

The `buildPython*` function computes name from `pname` and `version`.
This change removes `name` attribute from all expressions in
`pkgs/development/python-modules`.
While at it, some other minor changes were made as well, such as
replacing `fetchurl` calls with `fetchPypi`.
