[PATCH] tests/xfs/040: document purpose

[Luis R. Rodriguez]

Getting xfs/040 to "pass" takes a bit of effort, however the effort
to require updating xfsprogs is purely an xfsprogs maintainer task
only. There no functional gain by users of xfs or a QA team to get
this test to pass. This is not trivial from the current description
so document this.

 # compare-libxfs test
 #
+# The purpose of this test is only to nag the maintainer of xfsprogs to try to
+# keep xfsprogs's libxfs files in sync with the latest kernel's libxfs. There
+# is no functional need for anyone to actually run this test to confirm
+# proper XFS functionalilty, this is an xfsprogs maintainer test.
