[luci] [PATCH] ddns: make 'service_name' a ListValue

[Benoît Knecht]

Make 'service_name' a ListValue again, and add the empty string as a
possible value as this option is not required.
---

The 'service_name' option used to be a ListValue, but r5989 turned it
into a Value. This was presumably a mistake, so this patch reverts it
back.
