docker: generate chrome-vers.mk under agent-chrome build step

* Fixes an issue where chrome-vers.mk is not created when building
  but was created when publishing which broke things.

* Fixes an issue with generating chrome-vers.mk under a Mac.
  We use printf instead of echo, see [0].

* Make sure "latest" is inserted into chrome-vers.mk.
  The agent-bazel image uses chrome-vers.mk.
  Some images depended on agent-bazel and used "latest" but
  because "latest" wasn't in the file it failed to use the image.
  This issue is now fixed so that agent-bazel successfully
  creates a "latest" image locally.

Providing jobs

This project uses Jenkins Jobs Builder [1] to generate jobs from yaml descriptor files.

To add new jobs reuse existing templates, defaults etc. as much as possible. E.g. adding a job to build an additional branch of a project may be as easy as adding the name of the branch to an existing project.

To ensure well readable yaml-files, use yamllint [2] to lint the yaml-files. Yamllint can be downloaded using Python Pip:

pip3 install --require-hashes yamllint

To run the linter, execute this command from the project's root directory:

yamllint -c yamllint-config.yaml jenkins/**/*.yaml

Yamllint will not fix detected issues itself.
