chore(3p/lisp/cl-json): use quicklisp source r/4193

This switches upstream from hankhero/cl-json to
sharplispers/cl-json (the former of which had its last commit in 2014).
Sadly the new upstream hasn't decided on an appropriate fix for b/145
yet (due to concern about backwards compatibility, apparently). I did
not look before working on a fix, so I have an 90% finished fix which
is (I think) better than the already proposed ones, so I'll patch it in
here eventually.
