local-build: Standardise what's set for the local build scripts

We've a discrepancy on what's set along the scripts used to build the
Kata Cotainers artefacts locally.

Some of those were missing a way to easily debug them in case of a
failure happens, but one specific one (build-and-upload-payload.sh)
could actually silently fail.

All of those have been changed as part of this commut.

Fixes: #6908
