[LEDE-DEV] DDNS for ipv6

[e9hack]

Hi Christian,

I revert all ddns related changes. It looks like that the changes are not the root cause. I check my old log files. The
issue did start with my build from 16th of December.

Independently of this, I'm the opinion, ddns for ipv6 can't work with a deal-in or modem connection. My wan interface is
pppoe-wan. If the logical interface wan_6 is started, it (or pppoe-wan) doesn't have a global ipv6 address. It does only
have a link local address. The global address is assigned later. If the ddns script is started before the global address
is assigned, the script will be stopped and never restart.

Regards,
Hartmut
