cs configure: avoid --enable-shared problems
Building with shared libraries is not currently supported, because the Chez Scheme build is not set up to work in that mode, and because "stand alone" executable handling at the Racket level does not support Racket CS shared libraries. Also, there's no benefit to shared libraries. Racket executables get the benefit of sharing because they all run through the same executable. Meanwhile, there's not (yet?) a supported C API to make something like "libracketcs.so" useful. Related to #2993
