    gitlab-ci: ignore a bunch of directories.
    
    Problem with the CI is that the source is straight in our base directory
    and therefore installed dependency files as well as cache or built files
    are in subfolders.
    Let's try to ignore as much as I can see. This should avoid a bunch of
    warning and errors during report generation.
