fix for integration test for ECS Exec on Windows

This change fixes the following issues-
- Golang base image is Windows release specific and is not scalable. The change introduced here ensures that the correct base image is being used instead of the generic golang image. Also, we will build the binary and then copy it to the container image.
- We need to disable Go Module in order to build the binary. We enable it at the end of the script.
