[SPARK-22960][K8S] Revert use of ARG base_image in images

## What changes were proposed in this pull request?

This PR reverts the `ARG base_image` before `FROM` in the images of driver, executor, and init-container, introduced in #20154. The reason is Docker versions before 17.06 do not support this use (`ARG` before `FROM`).

## How was this patch tested?

Tested manually.
