Use qualified name for QT_MOC_EXPORT_PLUGIN() 

Using non-qualified name for QT_MOC_EXPORT_PLUGIN() breaks template
instatiation for QPointer<T>::operator=(T*) in qt_plugin_instance()
when the class is embedded a namespace with the same name.

namespace Test {

class Test : public QObject
{
    Q_OBJECT
    Q_PLUGIN_METADATA(IID "Test")

public:
    Test(QObject *parent = 0) : QObject(parent) {}
};

} // namespace Test

In function 'QObject* qt_plugin_instance()':
 error: expected type-specifier before 'Test'
 error: no match for 'operator=' in
        '_instance = (int*)operator new(4u)'
 note: candidates are:
