jlink error when building jextract on macOS for JDK 21

[Jorn Vernee]

Hey Manuel,

This looks like a strange error. I do not recognize it. The jawt header 
files are from java.desktop, and the jaxp.properties file is from 
java.xml. So, they should not be in jdk.compiler and jdk.internal.opt

If you list the contents of the jdk.compiler and jdk.internal.opt jmod 
files (using jmod list), are these resources listed?
