Fix qtnamespace compile break on Mac.

Appears as though the QT_NAMESPACE macros are incorrect here.

In fact in qisenum.h because the #define is no respecter of a namespace
in most of these conditional compile cases they will be ignored
effectively. The QT_HEADER also - if qtypetraits.h conditional compile
occurs then it will result in adding extern "C" { twice.  For the macros
invoking them will not cause the extern "C" { to be used anyway, so just
remove this altogether.
