[racket] Configuring packages' search paths for dynamically linked libs

It's probably easiest to add a link (named "libcairo.2.so") to the
Racket-specific Cairo library in the directory reported by

 #lang racket/base
 (require setup/dirs)
 (find-dll-dir)

Racket looks for dynamic libraries in that directory first, and other
programs won't look there.
