QtNetwork (examples) - update broadcastsender

Fix copyrights, update signal-slot connection syntax, use some simple
C++11 features (member-initializers, 'auto'), delete some data-members
(where a local variable is enough), where possible - use data-memebrs
as sub-objects (instead of heap allocated).

Task-number: QTBUG-60628
