    .gitlab-ci.yml: Remove unneeded care in the build instructions
    
    Now we revision junction.refs separately, there is no need to do
    a sed job on project.conf, we dont want to explicitly track
    freedesktop-sdk-junction because we want to explicitly revision it,
    and there is no longer any need for the --except line in `bst build --track-all`.
