Restore debian7 images needed for beats 7.17

[mauri870]

Beats 7.17 has no further planned releases, but we must remain ready for potential emergency patches.

Given this policy, we also aim to keep up with newer Go versions. PR #510 removed debian7 and debian8 images, causing failures when we upgraded 7.17 to go1.24.3. We cannot migrate to debian 9-11 due to glibc 2.13 constraints.

That said, restore the debian7 images to fix our 7.17 builds.

Relates elastic/beats#43984.

We can use 1.23, since it's a supported line and it already contains the support for Debian7, see #611

I prefer we don't bump 1.24 in beats@7.17 as long as 1.23 is a supported golang version. #509 was the agreement and some further details can be found at #510

Yes I remember that discussion now, but had forgotten it until we had put some work into getting the automated PR to bump 7.17 to Go 1.24.

Go 1.23 will go EOL in August I think, so we can safely keep 7.17 on Go 1.23.x until then without issue.

I don't think there is a burning reason to go to 1.24 in 7.17 so we can keep the original agreement to stay on 1.23 there.

[cmacknz]

OK, we need to keep 7.17 releasable until January 2026 which means it will will live past the EOL date of Go 1.23. We need this change but we don't need it urgently.

unrelated co failures, see #615

I think we need to exclude running those other pipelines for changes in the main pipeline, so I'll raise a PR to avoid that scenario.
