QtNetwork (examples) - update the fortune server example

Unlike client, this needs a bit more changes:
- remove redundant (and outdated) stdlib.h includes
- use QRandomGenerator (instead of qsrand/qrand pair)
- replace QStringList with QVector<QString>
- Q_NULLPTR->nullptr, ExplicitType * -> auto
- fix some weird indentation

Task-number: QTBUG-60628
