iptables: fix invalid symbolic link for ip6tables-apply
The iptables-apply is not installed which makes ip6tables-apply as an
invalid symbolic link:
$ ls -l /usr/sbin/ip6tables-apply
lrwxrwxrwx 1 root root 14 Jun 11 08:27 /usr/sbin/ip6tables-apply -> iptables-apply
$ ls -l /usr/sbin/iptables-apply
ls: cannot access '/usr/sbin/iptables-apply': No such file or directory
Backport a patch to fix the issue.
