Remove unused local variable from c_type_print_base_struct_union

In my earlier patch to remove TYPE_FN_FIELD_STUB, I didn't notice that
the local variable mangled_name_holder is now unused and can be
removed.  The compiler didn't notice, either, I assume because it has
a constructor and destructor.
