fix: add --add-opens JVM options for JDK 17+ in startup-native.sh

[lexburner]

Summary

• startup.sh already adds --add-opens flags when Java >= 9, but startup-native.sh was missing them
• This causes InaccessibleObjectException on JDK 17+ when using the distribution package startup script
• Added the same three --add-opens options to keep both scripts consistent:
  • --add-opens=java.base/java.lang=ALL-UNNAMED
  • --add-opens=java.base/java.lang.reflect=ALL-UNNAMED
  • --add-opens=java.base/java.util=ALL-UNNAMED

Test plan

• Verify startup-native.sh launches correctly on JDK 17+
• Confirm no InaccessibleObjectException on reflection operations
