[PATCH v3] fstests: btrfs: fix 006

[Anand Jain <anand.jain@oracle.com>]

btrfs fi sync /mnt, now does not output anything for success,
so the 006.out should be updated.

This change in btrfs-progs was introduced in the commit
 b005ca024990569d2de459485682158633937928
   btrfs-progs: fi sync: make it silent by default
 which was integrated at btrfs-progs version v4.5.2

Signed-off-by: Anand Jain <anand.jain@oracle.com>

 v2: Update commit log to indicate the btrfs-progs version at
    which sync UI is changed.
 v3: Drop _runnt_btrfs_utils_progs(). fi sync will error stdout
     on error, so don't need. Thanks Eryu.
