media/tree: Force "wget" user-agent in SoupSession
Spoiler alert, it'll sound insane ... because it is insane. Some servers treat libsoup user-agent differently than how they treat wget user-agent.
After a talk with Patrick Griffis, he mentioned that: "I imagine there isn't too much of a problem pretending to be wget. I would guess the assumption by these services is 'A CLI tool is downloading us and not a browser' rather than 'wget has unique behavior'.".
Knowing that, let's force "wget" as user-agent on our side.
