appstream: Address some problems

* Instead of using the kcm to signify kde connect, just call it kde
org.kde.kdeconnect. org.kde.kdeconnect.kcm.desktop didn't exist anyway.
* Specify launchables for optimal integration in software centers.
* Specify which dbus service it's offering, in case it ever is
necessary.
* Specify the oars, stating there's no offensive content of any kind
offered through KDE Connect.
