Makefile: add contrib already for autoloads so that uncompiled can have contrib/, too

* mk/targets.mk: Add contrib files already for autoloads so that
  uncompiled can have contrib/lisp/ added, too.  Remove all files from
  contrib/lisp/ that are found in lisp/ for `cleanlisp´ so that
  switching between different contrib configurations becomes easier.
  Remove variable ORG_TO_LISP since it is not needed anymore.
