nss: Fix tst-nss-files-hosts-long on single-stack hosts (bug 24816)
getent implicitly passes AI_ADDRCONFIG to getaddrinfo by default. Use --no-addrconfig to suppress that, so that both IPv4 and IPv6 lookups succeed even if the address family is not supported by the host. Reviewed-by: Carlos O'Donell <carlos@redhat.com> (cherry picked from commit c75d20b5b27b0a60f0678236f51a4d3b0b058c00)
