…chive.apache.org

### What changes were proposed in this pull request?
Try downloading orc-format from dlcdn.apache.org before archive.apache.org

This replaces #1820 which required dlcdn to have the current version.

### Why are the changes needed?
https://archive.apache.org/ discourages heavy use, and its rate limits can cause CI systems building Apache ORC to be banned.

### How was this patch tested?
It builds from a clean repo

### Was this patch authored or co-authored using generative AI tooling?
no

Closes #1830 from progval/dlcdn2.
