widl [2/2]: Make structs containing user types bogus; fix square_test_us test failure

[Dan Hipschman]

This fixes the square_test_us test.  This test failure turned out to be
much simpler to fix than the one with the conformant arrays; if I had
known, I would have just done this one first.  The problem was that
structures with user types weren't being recognized as complex.  In this
case, that meant that the structure was block copied.
