tomgon: archive artefacts even on build failure

The `tf-a-builder-tfa-next` job currently neglects to archive build
artefacts if the job fails, as the artefact directory is not copied
to the job workspace until *after* the script has exited with a
failure.

 * mimic what the `tf-a-builder` job currently does.

Rather than copying the artefacts directory to the workspace, symlink
the artefacts directory to where Jenkins expects it early on,
such that they are always available to Jenkins regardless of where
the build fails.
