Removing a bad Xbootclasspath hack, which breaks narwhal.

This was a bad idea when it came about, but it now actively breaks Java on
any platform which doesn't have rt.jar in
/usr/lib/jvm/java-6-openjdk/jre/lib. Which soon will be all of them (with
JDK 7), but it has been for a long time the case on Fedora/RHEL.
