Hi Guix!

This short patch adds a CLASSPATH native-search-path to our icedtea and
openjdk packages. It lets users build java on their machine using
Guix-provided dependencies and the JVM/JDK won't complain anymore it
can't find the dependencies :)

Unfortunately, this requires rebuilding all of Java, so it should go to
staging. I tested the patch on my computer and rebuilt all packages up
to java-jmh. No breakage to report, except a two undeterministic test
failures in jmh and commons-collections4.
