XRay works, but build fails with EOF error

Image marklambert/nextpvr-ccextractor

This image will eventually fail for other reasons because it uses .NET runtime, but this analysis failure should probably be looked at separately.

Reproduce the failure with the reported docker-slim build command and image. Start at internal/app/master/inspectors/container/container_inspector.go:255, where dockerutil.BuildEmptyImage reports the dockerapi.BuildImage unexpected EOF. Done means the image analysis proceeds without this EOF failure.
