squid: conditionally set status of CVE-2024-45802

According to [1] the ESI feature implementation in squid is vulnerable
without any fix available.
NVD says it's fixed in 6.10, however the change in this release only
disables ESI by default (which we always did via PACKAGECONFIG).

Commit in master branch related to this CVE is [2].
Title is "Remove Edge Side Include (ESI) protocol" and it's also what it
does. So there will never be a fix for these ESI vulnerabilities.

We should not break features in LTS branch and cannot fix this problem.
So ignrore this CVE based on set PACKAGECONFIG which should remove it
from reports for most users. Thos who need ESI need to assess the risk
themselves.
