Avoid regenerating classpath cache.

Note, when running a new Polygott container, in order for `clj`/`clojure`
command to find and use the classpath cache and the Maven artifact cache
generated during the time the Polygott container image is built:
  1) the container needs to be run as user `runner` in group `runner`
     (i.e., with `--user runner:runner`)
  2) `polygott-lang-setup -l clojure` needs to be run first inside the
     container before running any other Polygott command
     (e.g., `polygott-self-test`, `polygott-survey`, and `run-project`)
