1801121 - Point `fetch-zlib` task at the "fossils" directory

Status: ASSIGNED

(Firefox Build System :: Task Configuration, task)

Description

[Andrew Halberstadt [:ahal]]

The fetch-zlib task points to a build at the root of zlib.net, e.g:
https://zlib.net/zlib-1.2.13.tar.gz

However, when a new release comes out, the zlib maintainers remove that build and replace it with the newer version. This breaks the fetch task which we don't notice until it expires or we rebuild cached tasks, resulting in bugs like:
https://bugzilla.mozilla.org/show_bug.cgi?id=1798976
https://bugzilla.mozilla.org/show_bug.cgi?id=1800970

The latest build also exists under https://zlib.net/fossils, so we should just link there from the outset as the URL is stable. The downside is they don't keep gpg-signatures around for the older builds, so we'll have to remove that.

Attachment: Bug 1801121 - [ci] Point 'fetch-zlib' task at a stable URL, r?glandium!

The build at the root of zlib.net gets replaced whenever a new version is
released, thus breaking the fetch task. The build under fossils is stable,
though there doesn't appear to be any gpg signature.
