library/perl: drop ppc64le and s390x from _all_ stretch builds

cf
https://github.com/docker-library/official-images/pull/9496/checks?check_run_id=1766648538
and
https://github.com/docker-library/official-images/pull/9496/checks?check_run_id=1766752691

Based on Docker Hub listings these archs have not been updated for 8
months until now, so I assume that official-images build tooling has
dropped support for them as well...
