Makefile does not always use `DOCKER_COMPOSE_ENV` var (#1759)

Let say that you add a `/src/adservice/Dockerfile.elastic` to the project to build a specific version of the image.
So you add the following line to the `.env.override` file:

```env
AD_SERVICE_DOCKERFILE=./src/adservice/Dockerfile.elastic
```

If you run:

```sh
make redeploy
```

The `/src/adservice/Dockerfile.elastic` should be used instead the default one.

This commit adds `DOCKER_COMPOSE_ENV` variable anywhere it's needed.

Closes #1758.
