Fix some function lengths in the test suite (#45)

These tests appear adapted with memory64 with overlong LEB-encodings but
when merged with the upstream spec test suite the function length is too
short. By ensuring the function length is correct it ensures that the
only error in the module is the overlong LEB encoding.
