Qt5 static_cast bitmap data should be enough

This failed to build to on Haiku with:

/sources/core/vcl/qt5/Qt5Bitmap.cxx:
 In member function 'virtual bool Qt5Bitmap::Create(const SalBitmap&, sal_uInt16)':
/sources/core/vcl/qt5/Qt5Bitmap.cxx:155:92:
  error: invalid cast from type 'unsigned int' to type 'sal_uInt32 {aka long unsigned int}'
                *image_data = reinterpret_cast<sal_uInt32>(colorTable.at(*buffer_data >> 4));
