kde/spacebar: new aport (and it's dependencies)

An SMS application for Plasma Mobile, finally 🎉

Please note that it's still in development, and it doesn't work flawlessly yet. For example new chats can't be initiated, someone else has to send an SMS to you first before you can send an SMS back. However, with this application basic phone functionality should work with Plasma Mobile. I'll keep it up-to-date while it develops, just like the other to-be-released Plasma Mobile applications we already package (e.g. Plasma Camera).

I've also removed telepathy-glib from our packages, as it's now packaged in Alpine Linux.
