Minor edits

Makefile
config.mk
---------
  o Bump JJB_VERSION string from (default=2.8.0) to 3.2.0.
  o Consistent 'make lint-jjb' behavior for interactive and jenkins.

jjb/shell/shcheck.sh
--------------------
  o Cosmetic edits, curious to see if shellcheck linting is triggered
    by the repo:ci-management jenkins job.
