gnu: Separate potassco packages into their own module.

* gnu/packages/potassco.scm: New file.
* gnu/packages/maths.scm (libpotassco, clasp, clingo, python-clingo)
(python-telingo): Move to potassco module.  Adjust imports accordingly.
* gnu/packages/emacs-xyz.scm (emacs-pasp-mode): Move to potassco module.
* gnu/local.mk (GNU_SYSTEM_MODULES): Add %D%/packages/potassco.scm.
