Florian Müllner c0861b1227 gdm: Handle absence of Fprint.Manager service
We rely on the service to detect whether a fingerprint reader is
present. It is fine to not support fingerprint authentication
when the service is missing, but currently we don't handle this
case at all and end up with a non-functional login screen.
