Subject: [PATCH] batik: refactor

* All JARs end up in $out/share/java, and a few wrappers for the
  applications are made in $out/bin (closes #50932).
* stdenv -> stdenvNoCC, since no compilers are needed in any stages.
* Remove the vendored Rhino JavaScript engine and replace it with our
  Nixpkgs one.
* Add the stripJavaArchivesHook.

This is hopefully a large improvement over the previous derivation
(which simply copied the binary tarball into $out).
