t_immutable cannot be run twice on the same test directoty, because
append-only directory tests create files in append-only.d and those
file already exist from the first run.

Use separate test directories for the first and second t_immutable runs.

While working on the kernel fix, I found this test bug.
Please merge this test bug fix in preparation of the kernel fix.
