Update jitsi/jitsi to jitsi/jitsi-universe@205c971

The project jitsi/jitsi started listing an explicit org.jitsi.libjitsi
artifact version in order to comply with our policy which was put into
effect in our other projects. Now jitsi/jitsi-universe does not have to
specify any default artifact version for org.jitsi.libjitsi.
