Small update to makefile for CMUCL



The makefile for maxima pre59 says:

cmulisp-compile:
	echo '(progn (load "compile-cmulisp.lisp")(compile-maxima))' | ${CMULISP}

I think we should either

o add (quit) to the end of the progn
o add the -batch flag after ${CMULISP}

The former will work on all versions of CMUCL.

Without one of these, we are left at the prompt, which is probably not
what we want.

But I'd rather have the defsystem version instead.
