v-m: blackbox: Force TCP probe to IPv4
Since I added an IPv6 ULA prefix to the "main" VLAN (to allow communicating with the Synology directly), the domain controllers now have AAAA records. This causes the `sambadc` screpe job to fail because Blackbox Exporter prefers IPv6 by default, but Kubernetes pods do not have IPv6 addreses.etcd
