Hardcoded port config in EmbyServer service configuration

[stwarr 1]

The service config file (EmbyServer.sc) hardcodes the default ports that synology/Emby is expected to use (http:8096 / https:8920), but these values have no connection to the ports that are actually assigned in the Emby Dashboard/Network UI page.  Consequently, synology/DSM reverse proxy always reports that ports 8096/8920 are unavailable, regardless of the actual Emby configuration.
