TestRunCidFileCleanupIfEmpty fails on windows/mac because the test runs
the command `docker run scratch` and it gives the following error:
Unable to find image 'scratch:latest' locally
Pulling repository scratch
511136ea3c5a: Download complete
FATA[0004] 'scratch' is a reserved name
I am not entirely sure if this is a test issue or not but I had a quick
workaround by creating another image using `FROM scratch` and using that.
