github-actions: Use stratergy and if to deduplicate steps.

This is a fine solution short-term until github implements the
yaml anchors support. The limitation of this method is that we
cannot re-use most of the steps again for production install test
builds.

Thanks, Anders for this solution.

Verifying everything is migrated correctly is a pain. This script
ensures everything is done correctly (previous commit message
contains explainations for the steps being ignored if; in case
of github-actions steps they are ignored because they are actions
specific):
"""
This script prints out the ignore steps first. Then
prints out each step of both circle and actions side-by-side.
One step is out of order for bionic but verfying correction is
still easier. Format:
Actions: Install dependencies
Circle CI: install dependencies
....
