cmp: Fix the broken "too few arguments" error messages for mapcar and friends

This fixes #188 (closed).

The C-compiler "too few arguments" error messages for mapcar and friends were really broken: #'program-error was used instead of 'program-error, firt was used instead of first and the format arguments weren't in a list.

Before we would get this obscure error message:

> (defun oops () (mapcar #'1+))
OOPS

> (compile 'oops)
;;; OPTIMIZE levels: Safety=2, Space=0, Speed=3, Debug=0
;;;
;;; Error:
;;;   * The macro form (MAPCAR #'1+) was not expanded successfully.
;;; Error detected:
;;; The function PROGRAM-ERROR is undefined.

Now we get

> (compile 'oops)
;;; OPTIMIZE levels: Safety=2, Space=0, Speed=3, Debug=0
;;;
;;; Error:
;;;   * Too few arguments to function MAPCAR in form: (MAPCAR #'1+)

Also now cmperr is used instead of si::signal-simple-error. This is consistent with other error messages like

> (defun whoops () ((lambda (x))))
WHOOPS

> (compile 'whoops)
;;; OPTIMIZE levels: Safety=2, Space=0, Speed=3, Debug=0
;;;
;;; Error:
;;;   * Too few arguments for lambda form (LAMBDA (X))
