Ah, but that affects only systems that haven't already been "found" by
asdf. What does the following code produce when you run it just after
you started your Lisp?

  (loop 
     for key being each hash-key of asdf::*defined-systems* using
(hash-value system)
     do (format t "~%Found system ~s in ~s" key
(asdf::component-relative-pathname (cdr system))))

It pretty much seems as if the cffi system was already found by asdf -
altering the central registy will only affect systems not yet found.

Most likely because CLISP dosen't come with a pre-defined place where
asdf looks for systems. Just to make shure you aren't hunting ghosts:
your SBCL image does not contain any traces of asdf system objects?
