[PATCH] xfstests: update filters and output of btrfs/006

The btrfs-progs tools changed the output:
- 100GiB instead of 100GB
- The number of spaces was changed

makes sense

But for the rest, is the output change intentional, or sloppiness/accidental?

If it''s really intentional, then:

Thanks for the review, Eric!

Since this commit is not yet added to the repo, I just took the time to
create a cleaner fix.

The tools didn''t change the number of spaces in the output. The root
cause was that I had 11 devices in SCRATCH_DEV_POOL for the first time.
And this caused changes in the number of spaces in the output wherever
things like %4d was used.

One problem was the output of "uniq -c" which added spaces depending
on the size of the count value (e.g. one space less for 10+ devices).

The second problem was that "btrfs fi show" was doing the same:
"devid %4llu size %s used %s path %s".

Please scratch this patch out, I''ll send two better patches instead
which address the real problems.
