In older Linux kernels, requesting an extended attribute which cannot exist
failed with EPERM. In version 3.0, this was changed to ENODATA so that
programs can distinguish between missing attributes and permission problems
independent of the file type.
For example, lgetxattr("file", "user.name", NULL, 0) will now return ENODATA if
no such attribute exists even if "file" is a symbolic link.
In test 062, to make it work on kernels before and after 3.0, accept either of
the two error results from getfattr.
