Subject: [PATCH 94/99] fix: tests/functions: add macro HOST_SUPPORTS_IPV6

Check for the ipv6 sysctls to see if IPv6 is available. While nftables
allows addidng ip6 rules even if ipv6 is disabled, firewalld will also
try to set some sysctls which fail.

(cherry picked from commit f9ede55708e3cb325c1052b7c68f3346c8c8c63f)
