Fix Postfix mynetworks if IPv6 is disabled
If a deployer sets disable_ipv6 = yes, we should ensure that the mynetworks directive in /etc/postfix/main.cf contains only IPv4 addresses. The `newalias` command fails if IPv6 addresses appear in mynetworks but IPv6 is disable system-wide. Closes-bug: 1538268 Change-Id: I45f09d631e9b81554f8463851143fd27c9f51ead
