[racket] raco setup broken if behind softlink

The `raco setup` and `setup-plt` programs are the same, and the program
decides how to treat arguments based on the name used to run it. Since
your link is not called "raco", then it uses `setup-plt` mode, which
treats arguments as file names instead of collection names.

You can work around the problem by supplying `-l` before
