fans:monitor:witherspoon: Enable JSON config

Use the installed `config.json` as the fan monitoring configuration to
load at runtime. This replaces the need of the build time YAML
`monitor.yaml` configuration.

Tested:
    `monitor.yaml` removed from build image staging location
    Built/powered on image using the `config.json` file
