[PATCH] shared/010: avoid dedupe testing blocked on large fs

[Zorro Lang <zlang@redhat.com>]

When test on large fs (--large-fs), xfstests preallocates a large
file in SCRATCH_MNT/ at first. Duperemove will take too long time
to deal with that large file (many days on 500T XFS). So move
working directory to a sub-dir underlying $SCRATCH_MNT/.

Hi,

Besides fix this issue, this patch fix another issue passingly. I left
a bad variable named "testdir" in this case. This patch can fix it.

If maintainer feels I should fix it in another patch, please tell me:-P

Thanks,
Zorro
