Backport of #8649 to rel-v9r0.

This allows STOMP MQ connections to resolve IPv4-only broker hostnames by using AF_UNSPEC while preserving the IPv6 preference when IPv6 addresses are available.

Validation:

  • PYTHONPATH=src:dirac-common/src /opt/dirac/pro/Linux-x86_64/bin/python -m pytest -q -o addopts='' src/DIRAC/Resources/MessageQueue/test
