extern fn-explicit-align test: don't use uint128_t

...which seems not to be available on some platforms.
Or maybe it is under a different name but I don't want to deal with that

Instead, use two u64s. This isn't exactly the same, but we already have
some coverage of the packed u128 case in another test, so it's not
essential to have it here.
