Update Kde packages (#9)

* remove duplicate package

* replace default phonon-gstreamer to phonon-vlc in KDE packages

phonon-vlc (this is the only maintained and supported Phonon backend for KDE apps that use Phonon for their multimedia needs; the alternative phonon-gstreamer has been unmaintained since 2013 and should not be shipped by default, or at all, ideally)
