This takes inspiration from:

* The Notebooks 2.0 Dockerfile, which comes from a default recent Kubebuilder template, at
https://github.com/kubeflow/notebooks/blob/notebooks-v2/workspaces/controller/Dockerfile

* The Red Hat build Dockerfile (that's the Cachito part) in an internal repository.

This change brings multiple improvements:

1. Dockerfiles are brought closer together, especially to the Red Hat build; previously, sourcing things in a stand-alone RUN command had no effect
2. The openssl fips-compatible library is linked into the manager binaries, to proactively address fips concerns
