overlays: downgrade-transmission: add derivation

Transmission is a BitTorrent client which features a simple interface
on top of a cross-platform back-end.
Feature spotlight:
* Uses fewer resources than other clients
* Native Mac, GTK and Qt GUI clients
* Daemon ideal for servers, embedded systems, and headless use
* All these can be remote controlled by Web and Terminal clients
* Bluetack (PeerGuardian) blocklists with automatic updates
* Full encryption, DHT, and PEX support
