[test] accept any size for signature of .cxx methods in objc_subclasses

The size of the signature for .cxx_construct and .cxx_destruct varies
with the bitness of the target (the signature on 32-bit platforms is one
character shorter than on 64-bit targets), and IRGen/objc_subclass.swift
is the only ObjC test with .cxx_{construct,destruct} methods that runs
on both.
