add load_native_libraries entitlement to java.desktop (#124852)

The ingest-attachment module uses Tika to parse some content; Tika in turn uses some libraries from java.desktop to perform its tasks.

In turn, the JDK loads one (or more) native libraries for its implementation as part of class initialization. This means we need to grant load_native_libraries to java.desktop so that because AWT can load libraries for itself.
