reject cross-origin go2rtc stream requests in /auth

The go2rtc websockets and the webrtc offer POST still accepted any Origin, since go2rtc runs with origin "*" and /auth grants admin on the internal port, so a page on another site could pull live video through a LAN user's browser. nginx now passes Origin, Host, X-Forwarded-Host and Upgrade to /auth, which rejects a websocket upgrade or go2rtc stream request with a foreign Origin before the internal-port early return. The hostname rule moves to frigate/util/origin.py so /auth and the ws4py servers share it.
