[racket] tips for raco distribution

"raco exe" and "raco distribution" just worked well for installing my 
first ``Racket-based appliance''.

The two small problems I had were: (1) the "raco distribute" output tree 
contained paths from "define-runtime-path" that varied based on the 
absolute path of the build directory; and (2) when "define-runtime-path" 
was a directory, I couldn't exclude any files in that directory from 
being included in the distribution.

There might be a better way to do this, but the following Makefile 
worked for me (on GNU/Linux).  It just uses a separate build tree for 
"raco exe" and "raco distribute", controlling what files get into the 
build tree, and keeping the absolute path of the tree constant between 
runs so that the installed tree structure is constant between installs.
