scapy uses socket.has_ipv6 as part of its logic, but socket.has_ipv6 is True even when the system is started with ipv6.disable=1.

Sorry for not having spotted that this is a duplicate of #4541, I did make an effort to find whether this issue had already been reported but it somehow didn't show up in my search results, therefore I thought that nobody had reported this yet.

I confirm that #4560 is also a fix for the case that I reported. Thanks for looking into this.
