[PATCH v2 xfstests resend 2/3] generic/002: clean up the test

[ChenXiaoSong <chenxiaosong@chenxiaosong.com>]

From: ChenXiaoSong <chenxiaosong@kylinos.cn>

Add the hardlink group and use shorter loops. Use _exit() and change
the success text to "Silence is golden".

Suggested-by: Zorro Lang <zlang@kernel.org>
