Presents as an InternetGatewayDevice (but isn't?)

[ajorg]

I noticed that the NanoKVM Cube, on the latest release, is showing up as an InternetGatewayDevice (IGD). This turns out to be because it's running ssdpd is running.

It makes sense for it to advertise itself, for the presentation URL, but not as an IGD.
It should probably advertise itself as some other device or service from https://openconnectivity.org/developer/specifications/upnp-resources/upnp/
