DDNS_spDYN: switch to wget and more

* Update DDNS_spDYN.sh

- Switched from curl to wget
- Switched to spDYN for IP check
- Removed unused code

* Shift cron by 10 minutes

Advantages are that it is not executed at the same time as Nextcloud cron, and that changes in IP address, that are presumably done at full hours, are detected quicker.
