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
