Allow to build docker images offline (do not always use `docker build --pull`) 

Passing `KUBE_BUILD_PULL_LATEST_IMAGES=n` will disable building the artifacts
with `--pull`, so they can be built in an offline environment.

By default, `KUBE_BUILD_PULL_LATEST_IMAGES` is `y`, so the default behavior
is kept unchanged.
