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:
```

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.
