cs: make "main.sps" work in script or boot mode

Browse Source 
Now that Chez Scheme supports libraries in boot files, make
"racket.so" work when it is converted to a boot file. Loading it as a
boot file can save around 20ms on every major GC, since the
"racket.so" code will be in the static generation.

For now, however, `racketcs` is not set up to use "racket.so" in boot
form.
