Rework the toxchat/bootstrap-node Docker image.

* Use fully static build for the bootstrap daemon.
* Store a sha256sum of the binary in the repo.
* Updated documentation for it.
* Add support for fully static build in cmake.
* Enable the docker build on every PR, so we catch changes to the
  checksum. I realise this is adding toil, but having the checksum is
  valuable for security of released binaries.
