Updated the hardcoded dependencies

[yashsingh74]

The PR fixes the following changes-

• Allow default run args -it to be overridden by specifying DOCKER_RUN_ARGS.
• Introduce GO_IMAGE and GO_VERSION to allow the compiliation docker image to be specified.
• Add logic to handle the case where a non alpine golang image is used so that the script no longer blindly attempts to apk install bash and tar. Scripts checks for presence of both commands.
• Avoid using dos2unix, use sed
