bug fix: fix auto upgrade error message.

re: https://github.com/Neilpang/acme.sh/releases/tag/2.8.5

2.8.4 was skipped, but covered:

• Avoiding autoupdate by checking master hash value.
• more dns api support
• adapt recent letsencrypt ca http headers changes.
• bugs fixes.

While here, add in a lot of things missed in previous version of this port.
Look in share/examples/acme.sh/deploy,dnsapi,notify

Sorry about that.
