[racket] raco setup parallel build

I think i just misread the docs. I somehow though that PLT_SETUP_OPTIONS  
also works for directly calling raco setup which is obviously wrong. When  
i use -j it works as expected. Sorry for the trouble.

As a side note, maybe it's worth to specify these defaults in the docs for  
raco setups -j option, e.g
"By default, raco setup uses (min (processor-count) 4) on 32bit-systems  
and (min (processor-count) 8) processors on 64bit."
