configure: add --enable-embedfw for Mac OS

Building with `--enable-embedfw` creates executables that link
statically to the Racket runtime system, instead of linking to a
Racket framework, and that embed boot files in the case of Racket CS.

Executables built this way are meant to cooperate better with code
signing.
