[ObjC] Fix another case where a category's class name was not being resolved

Handle the case where the `class` field of the category is a direct
reference to an external symbol via a bind fixup. In that case, the
pointer's value when read from the view is 0. To determine the class
name it is necessary to look up the relocation for the pointer's address
and parse the class name from the symbol's name.
