[bug#54311] [PATCH] gnu: tint2: Update to 17.0.2.

[Tobias Geerinckx-Rice]

What Maxime means is that some forges (like GitHub) generate these archives on 
the fly, instead of the author uploading a 'stable' file.  You can usually tell 
them apart by the URL, but I forget GitLab's conventions.

These archives might be cached for a while but if they are regenerated the hash 
could change even if the unpacked data didn't.  This has happened in the past 
and breaks e.g. guix time-machine even if 'fixed' on master.

Hence we prefer git-fetch when available, or tarballs that look human-generated.

Kind regards,
