When a native Phar manifest contains duplicate filenames,`zend_hash_add_mem()` fails to insert the duplicate entry and does not take ownership of its allocated filename and metadata. And cause the memory leak since it can't be freed.

The fix is quite simple tho. Check the insertion result and release these allocations on failure.
