Removed -mindepth 1 from find.

It was not working on my Ubuntu when adding the following to .bashrc:

`export CLOJURE_EXT=$HOME/.m2/repository/org/clojure/clojure/1.6.0/clojure-1.6.0.jar`

Maybe I was not using it in the right way, but I found that removing -mindepth 1 makes `find` work with individual jars as well as folders (tested on GNU bash, version 4.3.11(1)-release (x86_64-pc-linux-gnu) only).
