Correct the definition of the multilabel flag: it enables multilabel

MAC support on the file system, if supported, which causes MAC to treat
each object as having its own label, rather than using a single label
for all objects on the file system.  This doesn't have to be used in
combination with the tunefs/newfs flags -- it's an alternative.
