Classes in ${JAVA_HOME}/lib/valueclasses/java.base-valueclasses.jar jave a LoadableDescriptors attribute

https://cr.openjdk.org/~dlsmith/jep401/jep401-20251210/specs/value-objects-jvms.html#jvms-4.7.32

The contents of this attribute is not deterministic. If you build from the same JDK source code twice, you get classfiles that are different. This does not meet the requirement that JDK builds must be reproducible

$ make jdk

LoadableDescriptors:

$ rm -rf jdk
