tst_moc: fix build with GCC 12

Browse Source 
You can't mismatch the export macros. The QT_MOC_EXPORT_PLUGIN_V2 macro
defines these functions as Q_DECL_EXPORT so they can be found by
QPluginLoader. We must match the macro here, otherwise GCC 12 complains
(tst_moc.cpp is compiled with -fvisibility=hidden):

tst_moc.cpp.o: non-canonical reference to canonical protected function `qt_plugin_instance' in moc_plugin_metadata.cpp.o
