QIOPipePrivate: fix Clang's -Wfinal-dtor-non-final-class

Says Clang 15:

    qiopipe.cpp:39:23: warning: class with destructor marked 'final' cannot be inherited from [-Wfinal-dtor-non-final-class]
        ~QIOPipePrivate() final;
                      ^
    qiopipe.cpp:34:7: note: mark 'QIOPipePrivate' as 'final' to silence this warning
    class QIOPipePrivate : public QObjectPrivate
          ^

Apply the suggested fix. Cf. also
