tests/cpydiff: Fix test case for modules_json_nonserializable.

The test case was producing the following error:

    Traceback (most recent call last):
      File "<stdin>", line 12, in <module>
    UnicodeError:

which did not demonstrate the intended difference (this particular
non-json-serializable object DID throw an exception! just not TypeError).

The updated test uses a byte string with all ASCII bytes inside, which
better illustrates the diference.
