meson: explicitly check whether AF_INET6 is available 

We're currently not checking whether IPv6 is available before build,
so it just gets silently disabled if AF_INET6 is missing - even
when user wants to enable it explicitly. Adding explicit check into
meson.build, so failing when ipv6 option enabled, but no IPv6 supported.
