base-files: network.sh: properly report local IPv6 addresses

Browse source 
Rework the network_get_ipaddr6() and network_get_ipaddrs6() functions to
fetch the effective local IPv6 address of delegated prefix from the
"local-address" field instead of naively hardcoding ":1" as static suffix.

Fixes FS#829.
