[racket] customary sqlite3 binary

Putting the library in "~/.racket/6.0/lib/" should have worked.

What if you rename the library "libsqlite3.so.0" (i.e., with an
explciit version)? It looks like the search path in `raco exe` may have
the wrong nesting of path search versus version search: paths within
versions instead of versions within paths.
