Locally build runner image instead of pulling it (#473)

* Fix acceptance helm test not using newly built controller image

* Locally build runner image instead of pulling it

* Revert runner controller image pull policy to always

and add a line to the test deployment to use IfNotPresent

* Change runner repository from summerwind/action-runner to the owner of actions-runner-controller.

Also fix some Makefile formatting.

* Undo renaming acceptance/pull to docker-pull

* Some env var cleanup

Rename USERNAME to DOCKER_USER(is still used for github too tho)
Add RUNNER_NAME var(defaults to $DOCKER_USER/actions-runner)
Add TEST_REPO(defaults to $DOCKER_USER/actions-runner-controller)
