Subject: [PATCH] Revert ABI breakage in kiwix::Downloader::getDownloadIds()

Changing it to be `const` is an ABI change since the symbol changes from
`_ZN5...` to `_ZNK5...` (addition of "K").

The other changes made in 18b7b5f27 are probably fine to keep since they
don't appear to be used from what I can tell.

Fixes https://github.com/kiwix/libkiwix/issues/998.
