feat: Add null checks for JNI method arguments 

Adds a null pointer check for the origApkPath and cacheApkPath arguments in the enableOpenatHook native method.

Previously, passing nullptr to this method would lead to a potential crash. The added checks ensure the function handles invalid input gracefully by logging an error and returning early, thus preventing a potential crash.
