If we do not specify a configuration file for the "kas build" command,
the repository anchor is set to the current working directory,
which breaks the resolution of repo-relative include file paths
in the IncludeHandler class if repo root != current working directory.
Sets the repository anchor to the root path of the repository with
fallback to KAS_WORK_DIR if we use .config.yaml from KAS_WORK_DIR.
