hfsplus: remove unused routine hfsplus_attr_build_key_uni 

The directory/file catalog b-tree equivalent, hfsplus_build_key_uni(),
is used by hfsplus_find_cat() for internal referencing between catalog
records.  There is no corresponding usage for attributes - attribute
records do not refer to one another.
