main/{audit,dmraid,keyutils,libcap-ng}: packages fail to rebuild due to curl certificate error

Edit: this can be closed when the upstream server is consistently accessible again over curl/wget.

The following packages in main/ failed to rebuild due to a certificate error:

• audit-4.0.1-r0
• dmraid-1.0.0_rc16-r6
• keyutils-1.6.3-r3
• libcap-ng-0.8.5-r0

While this issue was initially about packages in main/, as noted in comments, the following packages in community/ have a similar issue.

• cachefilesd
• portablexdr
• virt-what

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the webpage mentioned above.

It was noted that the subdomain is not returning the full cert chain. Opening a new issue to track this separately from the GCC 14 rebuild efforts.
