Add attic-client (s390x) and geesefs to flake-hub, rewrite CI in xonsh

Move attic-client s390x cross-compilation from building/s390x/attic-client-s390x
and geesefs from building/s390x/geesefs-s390x into flake-hub. Replace ci/build.sh
with ci/build.xsh. All packages now built and pushed to attic via the existing
Woodpecker pipeline on push to main.
