fs: DeviceLister: Explicitely disable upnp & sap modules

VLC 3.0 doesn't seem to support multiple instances of the UPnP service
discovery module, and we won't discover anything valuable with it for
now anyway.
Also disable the SAP module since it won't discover anything we can use
from the medialibrary either.
