[Mirroring Service] Disable media remoting on non-Chromecast devices

Disable remoting on devices whose model names aren't "Chromecast*" or
"Eureka Dongle*" because remoting doesn't work on many other devices,
even if they support GET_CAPABILITIES.

Also fix the receiver info parsing code to parse into the right types.
