Fix make errors for Qt5

[kyunghwan-abel-bae]

I found 2 errors on make process.

(1) qiviservicemanager.cpp:308:89: error: no matching function for call to ‘QSet<QString>::QSet(QList<QString>::const_iterator, QList<QString>::const_iterator)’ const QSet<QString> newInterfaces = QSet<QString>(ifaceList.begin(), ifaceList.end());

iviservicemanager.cpp:315:100: error: no matching function for call to ‘QSet<QString>::QSet(QList<QString>::const_iterator, QList<QString>::const_iterator)’ const QSet<QString> interfaces = QSet<QString>(curIfaceList.begin(), curIfaceList.end()); (2) mediaplayerbackend.cpp:101:41: error: ‘class QMediaContent’ has no member named ‘request’ qCDebug(media) << m_player->media().request().url();

======================================================

I fixed them based on Qt5 supported functions. I hope you to check them.
