jlink error when building jextract on macOS for JDK 21

[Manuel Bleichenbacher]

Hi Jorn

All three conflicting files are present in both the jdk.compiler and
jdk.internal.opt jmod files. In the JDK 20, they haven't been present in
either jmod file.

What build of the JDK are you using for testing?

Regards
Manuel
