Draft: test artifact publishing

This is consistent with the job which builds the bundles.

This expands automatic updates to the SECO B68 board. Both new jobs
re-use existing generic jobs and contain no new logic.

The HawkBit instance needs to be configured externally and reachable
from the runner performing the publishing step. The location of the
instance must be provided through environment variables compatible with
hawkbitctl, namely HAWKBIT_{URL,USERNAME,PASSWORD}. HAWKBIT_TENANT is
optional and untested.

The bundle is added as an artifact to a new software module named after
the bundle, using bundle timestamp as the version. The module is then
placed in a distribution named after the image (not the bundle), with
the exact same version.

This allows the bundle job to be started even if just one of the jobs
in the previous stage, the one for pi4 image build, succeeds. This is
better for testing and allows jobs to start and finish faster, reducing
total build time.

The find call that was used to copy artifacts selected only files. In
some cases, bitbake generates symbolic links that are worth copying as
well. Extend the find expression to find both.

The --archive flag should help us preserve symlinks.
Add --verbose to make the process easier to debug.

Those timestamps are useful to create unique content in HawkBit
later on. We can always strip them if we want to, but it is hard
to re-create that information when it is not encoded in the file name.

This saves several gigabytes of traffic per build. Those artifacts
are automatically pulled due to being present in the previous stage.
Bundle is built from source, so no artifact is ever used.

The job extends the .build-image job so this part is automatic.
