Add tflint

[cyberox]

Include tflint in arkade. This would allow us to use it as part of our CICD pipeline to verify our terraform resources via the arkade-get Github workflow.

Expected Behaviour

Similar to any other tool – tflint: latest would be great, plus support to point it to specific versions.

Current Behaviour

A Pluggable Terraform Linter

Possible Solution

Add tflint to arkade

Context

We are currently using this tool in our CICD pipeline, so it would be nice to install it the same way as the other tools used in the pipeline.
