[RFH] fedora: pedantic fails complaining that awk is missing

GitHub Actions CI started failing the pedantic (fedora) job at the tip of 'master' few days ago, and the log claims the failure is due to missing "awk". Even though we have seen a few topics to rewrite Perl scriptlet, and I think at least one of them uses awk, but they haven't hit 'master' yet, so it is puzzling why this started failing all of a sudden.

So here is a band-aid. I wouldn't be surprised if the base image was updated without telling us. We have seen Ubuntu 20.04 base image retired to cause CI failures as well.

Almalinux does not even seem to have awk available as a package (or it may be called differently, but we are not suffering from the lack of awk on that platform anyway), so make sure we ask for awk only on fedora.

 * As the scheduled retirement of U20.04 image broke CI jobs running
   for 'master', I started looking at making it pass again with the
   minimum change, i.e. by merging dd/sparse-glibc-workaround and
   js/ci-github-update-ubuntu topics.

   Then I somehow found that another job is broken.  And this patch
   seems to make it work.  Not knowing how it got broken is
   unsatisfactory, though.
