Remove whirlpool from the list of CA/Cert digest algorithms as it does not work properly. OpenSSL claims it's not valid ("unknown signature algorithm"). Fixes #7370
While I'm here, stop needlessly repeating the algo list, it's a global in certs.inc, so use that single copy of the list.

Fix display of openssl errors when working with CA or certificate entries. Found this while looking into ticket #7370

Deduplicate code

Allow CloudFlare DDNS entries to use "" or "." for the hostname portion of the domain in the GUI to update the domain's @ record. Then in the backend code, remove that from the FQDN since CloudFlare doesn't like that to be sent explicitly. Fixes #7357

Fix is confirmed to work by two forum users: https://forum.pfsense.org/index.php?topic=122099.msg699763#msg699763
