testing/apptainer: upgrade to 1.1.0

• The change log states Apptainer no longer installs a setuid-root portion by default so I think we should provide a non-suid binary as well
• Trying to build for aarch64 and ppc64le again (we don't have suid binary now)
• There are tests actually (and a lot of them, both unit tests and e2e tests). I tried to make testing works but it looks kind of ugly :)

go test $(go list ./... | \
		grep -vF "/sysctl" | \
		grep -vF "/namespaces" | \
		grep -vF "/loop" | \
		grep -vF "/proc" | \
		grep -vF "/capabilities" | \
		grep -vF "/archive" | \
		grep -vF "/sif" | \
		grep -vF "/build/files" | \
		grep -vF "/sources" | \
		grep -vF "/cgroups" | \
		grep -vF "/instance" | \
		grep -vF "/security" | \
		grep -vF "/bin" | \
		grep -vF "/crypt" | \
		grep -vF "/env" | \
		grep -vF "/util/fs" | \
		grep -vF "/paths" | \
		grep -vF "/image")

Marking as Draft for now. Let's see how the pipelines go.
