Remove custom DNS propagation check

acme.sh handles DNS propagation checking internally via --dnssleep
and _check_dns_record. Custom propagation checks are unnecessary
and can conflict with acme.sh's own timing.

Removed:
- _opusdns_wait_for_propagation() function
- OPUSDNS_Polling_Interval option
- OPUSDNS_Propagation_Timeout option

Script is now consistent with other DNS API implementations
(Cloudflare, AWS, etc.) which don't have custom propagation checks.
