Trying to get arbitrary strings suitably quoted for shell, embedded in a
YAML file, processed by Python templating, is like seven bad ideas all
embedded into one big can of bees.
Reuse the same script we use for bare-metal to generate the environment,
tar that up into a per-job overlay which is added to the
inter-pipeline-reusable rootfs built by the container jobs and the
intra-pipeline-reusable overlay built by the build jobs.
@anholt wrote a chunk of this - replacing the $ENV_VARS GitLab CI
variable with a Python loop across the POSIX job environment - in
!11192, but this still had YAML quoting nightmares, and was more
needless duplication between LAVA and bare-metal.
The diff is large and annoying, but is mostly a sed job to get
ENV_VARS="FOO=bar BAZ=quux" into FOO: bar\nBAZ: quux.
