    gnu: Add emacs-ob-sclang.
    
    Remove emacs-org-contrib's dependency on SuperCollider by extracting
    ob-sclang.el into its own package.
    
    * gnu/packages/emacs-xyz.scm (emacs-org-contrib)[source]: Add snippet
    that deletes ob-sclang.el.
    [propagated-inputs]: Remove emacs-scel.
    (emacs-ob-sclang): New variable.
