[racket] raco setup parallel build

I don't think there's a limit for `-j' --- just maximum values for the
default.

I'm able to run `raco setup -j 5' on a 32-bit build and `raco setup -j
16' on a 64-bit build, and I don't see any limit in the implementation.
So, I'm puzzled that it isn't working for you.
