Reinitialize sun.security.pkcs11.P11Util at runtime

Fixes build error:
```
Error: Detected a java.lang.ref.Cleaner object in the image heap which uses a daemon thread that invokes cleaning actions, but threads running in the image generator are no longer running at image runtime.  To see how this object got instantiated use --trace-object-instantiation=java.lang.ref.Cleaner. The object was probably created by a class initializer and is reachable from a static field. You can request class initialization at image runtime by using the option --initialize-at-run-time=<class-name>. Or you can write your own initialization methods and call them explicitly from your main entry point.
Detailed message:
Trace: Object was reached by
  trying to constant fold static field sun.security.pkcs11.P11Util.cleaner
    at sun.security.pkcs11.wrapper.PKCS11.<init>(PKCS11.java:170)
  parsing method sun.security.pkcs11.wrapper.PKCS11.<init>(PKCS11.java:154) reachable via the parsing context
    at static root method.(Unknown Source)
