Subject: [PATCH] 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.
