Subject: [PATCH] fix: correct ObjC reference in Frida 17.x compatibility layer

Fixes a typo in the Frida version compatibility check where
globalThis.Java was incorrectly assigned instead of globalThis.ObjC.

This typo caused a ReferenceError when the agent attempted to use
ObjC methods on iOS devices running Frida 17.x, specifically when
calling env_runtime() and other iOS-specific functions.

The fix ensures that when globalThis.ObjC exists (Frida < 17),
it is correctly assigned to the ObjC variable instead of Java.

Fixes #740

Tested-on:
- Frida 17.0.7
- iOS 17.x (jailbroken device)
- DVIA-v2 test application
