Don't override msw.remap system option value in wxToolbook.

Introducing a system option for all toolbars and then ignoring it inside wx
itself is ridiculous and just goes to prove that this option itself was a
mistake. But as we have it, we should respect whatever value it's set to
(which should hopefully be 0 anyhow for most modern systems) instead of
overriding it forcefully making the mockery of the whole "option" concept.
