The kernel has historically written out symlinks this way and read them back in, so we're fixing that. The 1eb70 change came with change dbcc to fstests to adjust the golden output; since we're adjusting the kernel back to old behavior, we need to adjust the test too.

Wong This began as a regression test for the issues identified in "xfs: allow symlinks with short remote targets". To summarize, the kernel XFS code does not convert a remote symlink back to a shortform symlink after deleting the attr fork. Recent attempts to tighten validation have flagged this incorrectly, so we need a regression test to focus on this dusty corner of the codebase. However, there's nothing in here that's xfs-specific so it's a generic test. Signed-off-by: Darrick J.
