gnu: Remove python-pastescript.

It fails to build, no users in Guix.

Note from upstream:

  Paste Script is being maintained on life support. That means that
  critical bugs will be fixed, and support for new versions of Python
  will be handled, but other than that new features are not being
  considered.

* gnu/packages/python-web.scm (python-pastescript): Delete variable.
