Add shell script linters to ci_light flavor

[wesley-dean]

Use-case: many of my Docker-related projects have glue shell scripts (e.g., /entrypoint.sh) that are added to images (e.g., COPY entrypoint.sh /) that are run when the image is run (e.g., ENTRYPOINT ["/entrypoint.sh"]) and I would like to have them scanned without having to pull down the full scanner.

Fixes #1298

Add the BASH_* linters to flavors/ci_light/flavor.json

@wesley-dean legit request, but it has to be done using yml descriptors then bash build.sh :)
I'll update your branch to make it work :)
