On some hosts, IPv6 connectivity is limited and may result in DNS lookups returning IPv6 addresses that the host is unable to reach. Add a config file for glibc's getaddrinfo function that configures IPv4 addresses to have higher precedence for such hosts.

Fixes: #3950

Pushed an update to apply the same change to the rhel9-s390x machines. I've deployed onto all four test machines.
