Remove WX_DEBUG option from Unix wx presets, it's not needed any more.

It doesn't make sense to select debug or release build of wxWidgets any more
as they are now compatible under Unix. Under Windows the option is still
needed but it selects the build using debug (or not) version of the CRT rather
than the one built with __WXDEBUG__ defined.
