Marek noticed that some builds were failing with:

  + cd dist/install
  + find
  + cpio -R 0:0 -o -H newc
  ./automation/scripts/build: line 111: cpio: command not found
  + gzip

but succeeding overall, and producing a zero length xen-tools.cpio.gz as an
artefact.

In fact, it's all of:

  archlinux:current
  debian:12-x86_32
  fedora:41
  opensuse:tumbleweed
  ubuntu (all versions)

Add cpio into all of these containers, including opensuse leap for good
measure, and use pipefail in the build script.

Fixes: 4611ae6fb8f9 ("CI: save toolstack artifact as cpio.gz")
