Listen on IPv4 and IPv6

[porjo]

Dockerfile currently only listens on IPv4. This change makes it listen on IPv6 also.

Fixes #1138

Thank you, while not having "Docker" here, is this still working in case IPv6 is not available on a particular setup?

It's a good question. I tested like this:

docker run -it --rm --entrypoint /bin/ash --sysctl net.ipv6.conf.all.disable_ipv6=1 radicale
/app $ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
2: tap0: <BROADCAST,UP,LOWER_UP> mtu 65520 qdisc fq_codel state UNKNOWN qlen 1000
    link/ether b2:c9:0a:15:c2:ac brd ff:ff:ff:ff:ff:ff
    inet 10.0.2.100/24 brd 10.0.2.255 scope global tap0
       valid_lft forever preferred_lft forever
/app $ bin/python bin/radicale --hosts 0.0.0.0:5232,[::]:5232 &
/app $ netstat -an
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       
tcp        0      0 0.0.0.0:5232            0.0.0.0:*               LISTEN      
tcp        0      0 :::5232                 :::*                    LISTEN      

So the container indicates no IPv6 and Radicale starts without error when given the [::]:5232 hosts value.
