package/apache: update mirror url

While the 2.4.65 release of this package is available on
https://dlcdn.apache.org/httpd older version are removed from this
location in favour of https://archive.apache.org/dist/httpd.

In 2025.02.x branch the apache package hasn't been bumped to the latest
version yet so the following error started appearing on the autobuilder:

```
>>> apache 2.4.64 Downloading
wget -nd -t 3 --no-check-certificate -O '/workdir/instance-0/output-1/build/.httpd-2.4.64.tar.bz2.hfXgDB/output' 'https://dlcdn.apache.org/httpd/httpd-2.4.64.tar.bz2'
WARNING: The certificate is NOT trusted. The certificate issuer is unknown.

make: Leaving directory '/workdir/instance-0/buildroot'
```

To avoid running in the same error once the next package version is
released this patch update the site to the archive mirror with all the
releases.
