Recently LTP upstream removed some ext4 tests[1]. And two of them is still valid to keep. So I transport those two tests here. ext4-nsec-timestamps, which is used to test nanosec timestamps of ext4, rewrite into ext4/043 and 044. ext4-subdir-limit, which is used to test subdirectory limit of ext4, rewrite into ext4/045.
