There was a bug when a branch contained a slash then the file with
downloaded sources was not found. Update all, all images have to be
rebuilt and pushed to docker hub so the changes are applied inside
github actions.

The main script ci/images/test-build should be most up to date and
copied to all docker templates, sync them. Fix descriptions that were
copy&pasted from musl. Add missing test-build script from musl image.
