reproducibly_build_Tails_ISO_* Jenkins job are broken

Originally created by @intrigeri on #12579 (Redmine)

It would be nice to have CI again for reproducible builds, given we would like 3.0 to be reproducible (BTW I’m going to create a similar job for feature/stretch).

See e.g. https://jenkins.tails.boum.org/job/reproducibly_build_Tails_ISO_feature-5630-deterministic-builds/1/console: it seems that mv tails-* build-artifacts/ should be adjusted to the place where artifacts now land.

Parent Task: tails/tails#5630
