Amir Zarrinkafsh dc6fb7f5f2 ci(buildkite): stop the coverage build racing suites over its image tag (#13439)
Every agent shares one Docker daemon, and the coverage build used the
same `authelia:dist` tag that every suite's `pre-command` loads, retags
and removes. When another build's suites loaded their image between this
build's `docker build` and the `docker save` in `pre-artifact`, the tag
was gone (`reference does not exist`) or pointed at the other build's
image. Since `pre-artifact` had no `pipefail`, the failed save uploaded
an empty archive, the job passed and every suite in the build failed on
load.

The coverage image is now built under a per-job tag through a new
`--tag` flag on `authelia-scripts docker build`. `pre-artifact` takes
`authelia:dist` only to save the archive, inside the same lock the
suites hold around their load, and `pre-exit` removes the per-job tag.
With every write to `authelia:dist` under that lock, suites can no
longer pick up another build's image between their load and retag
either.

`pre-artifact` now fails the job when the save fails, and skips the save
when the build itself failed or was cancelled.
