ddns-scripts: remove minimum 5 minute wait

Browse Source 
To check if the update was successful.

Not all DDNS implementations have such huge latencies updating their services.

nsupdate for example, updates immediately and the update is immediately checkable.

Add new check_interval_min value to be able to set a check interval lower than the
previously hard-coded 5 minutes.

Fixes: #20564
