fix(scripts): Cleanup build version handling.

A few things here:
 - Source manifests/version.txt directly instead of coreos-version.sh
 - Remove Chrome branch from target image directory names.
 - Use proper version instead of timestap for catalyst builds.
 - Move lsb_release script from coreos-overlay to build_library.
