This allows configuring the TTL that is used for multicast packets sent out on the sockets, and is defaulting to 1 as before. The default might change at some point. In some networks multiple hops are needed to reach the PTP clock and this allows to configure GStreamer in a way that works in such networks. At a later time, per-domain or per-interface TTL configurations might be added when needed. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5649>
