Steeve Morin 5419e7a09d cmd/cgo: update JNI's jobject to uintptr check for newer Android NDKs
In Android's NDK16, jobject is now declared as:
    #ifdef __cplusplus
    class _jobject {};
    typedef _jobject*       jobject;
    #else /* not __cplusplus */
    typedef void*           jobject;
    #endif

This makes the jobject to uintptr check fail because it expects the
following definition:
    struct _jobject;
    typedef struct _jobject *jobject;

Update the type check to handle that new type definition in both C and
C++ modes.

Fixes #26213
