FQDN Proxy together running with Wireguard has an issue where proxied dns requests can cause a port collision. See: cilium/cilium#31535

Despite this, the actual fqdn tests seem to be resilient to this, likely due to retries.

While we work on a fix for this issue, let's add a temporary exception here.

There are cases where we want to ignore a specific error log that any relevant substring of may be too general and exclude logs we want to fail on.
This switches the except lists to use a logMatcher interface type that is implemented by both a string and regex matcher for log exclusions.
