Fix static plugin loading.

The QFactoryLoader::indexOf and keyMap functions expect to receive the
metadata that contains a "MetaData" entry, instead of the entry
itself.

Also, QFactoryLoader::metaData() skips static plugins with the wrong
IID, so we need to skip it too in QFactoryLoader::instance().
