[PATCH] du-k-works: update test case

[Kang Kai]

For ext3/4 image whose size less than 512M, this case fails.

When format a ext3/4 image without specifing the size of blocks -b,
mke2fs will determine block-size heuristically by the filesystem size
and the expected usage of the filesystem. If the image size less than
512M and no usage of the filesystem specified, the block size is set to
1024, so the output of 'du -k du.testdir':
on ext4:
81	du.testdir/
on ext3:
83      du.testdir/
These are the same results with output of du from coreutils.

Update test case to handle these situations.
