sd-dhcp-lease: fix handling of multiple routers
currently if a dhcp server sends more than one router, sd-dhcp-lease
does not copy the ip because it assumes it will only ever be 4 bytes. a
dhcp server could send more than one ip in the router list, so we should
copy the first one and ignore the rest of the bytes.
