ci: new true builder as a private package

This is useful for testing things with a builder that always succeeds. In
a project, use "devkit-admin build && npm install $DEVKIT_PATH/dist/___builder.tgz"
and you have a "@_/builders" package that contains a true builder.

This is not published on NPM so I scope this as ci.
