[VOL-5296] shellcheck and yamllint cleanups

jjb/shell/github-release.sh
---------------------------
  o Fixed a few lingering problems in source.
  o Cannot quote shifted arguments when creating a reference (local -n).
    + Passed values morph into a string with quoting so lose type.
  o Remove shellcheck exclusions, unqouting corrects the problem:
    + SC2178 - Variable was used as an array but is now assigned string.

jjb/lint.yaml
jjb/maven.yaml
jjb/verify/osam.yaml
--------------------
  o Peripheral edits to force a jenkins job to run for *.sh.
  o Cleanup errors reported by yamllint --strict.
