Although btrfstune will already warn users to make sure the fs is not
corrupted, we can never trust end users.
If the target fs has transid error, btrfstune can cause further damage,
thus we need to make sure btrfstune can safely reject fs with transid
error, other than ignoring the problem.
The image is copied from fsck-tests/002, just override check_image() to
run "btrfstune -u" instead.
