Unless there's a way to read out these limits, I'm not sure it's a good idea
to add a test like that to xfstests --- it's too fragile since at some point
we might change what those limits might be.

Also, xfstests is primarily intended to be a file system level stress tester
testing for correctness, and issues of whether we blow up on the 40th,
41st, or 42nd symlink seems more like an ABI issue --- and even there I'm
not sure the ABI specification should be quite that detailed over what's
allowed and not allowed.
