rgw: update last_added_entry when count == num_entries

RGWRados::cls_bucket_list_unordered() will produce one redundent entry
every time is_truncated is true.The issue could be easily reproduced
when a bucket is filled with amounts of incomplete multipart upload.
To be more specific, the number of incomplete multipart upload objects
should be greater than 1100.
