Add missing include in Cluster.pm

The postmaster test 004_negotiate.pl could fail due to IO::Socket::INET
gone missing, in environments that cannot use Unix sockets.

Oversight in the backport done in 6dffaeb8e54c, so like the other commit
this is applied across the v14~17 range.  Per buildfarm member drongo.

Security: CVE-2026-6479
Backpatch-through: 14
