[LTP] [PATCH v3] squashfs: Add regression test for sanity check bug

[Cyril Hrubis <chrubis@suse.cz>]

Hi!
Pushed with minor changes, thanks.

Apart from removing the needs_tmpdir I've also changed the TPASS message
to something more meaningful and move the TINFO message to setup so that
it's not printed on each iteration.
