build: Fix Zstd and Hiredis downloads for unstable GitHub archives

The content of the Zstd and Hiredis GitHub source achive URLs like
<https://github.com/$X/$Y/archive/$tag.tar.gz> apparently change from
time to time. Color me surprised. [1] says that this is intentional
(although, at the time of writing, reverted temporarily). Let's use
another URL for Zstd and not verify the checksum for Hiredis (since
there is no release source archive).
