Revert "Run fossa analysis in a distinct pipeline"

[ndeloof]

Reverts docker/app#670

Fossa CI build isn't reported to Github as Jenkins github multibranch plugin has commit status context hardcoded : https://github.com/jenkinsci/github-branch-source-plugin/blob/master/src/main/java/org/jenkinsci/plugins/github_branch_source/GitHubNotificationContext.java#L150

Impacted files detection within a PR is someway broken as https://ci.docker.com/teams-dsg/job/dsg/job/app-fossa/view/change-requests/job/PR-655/1/console states Stage "License Scan" skipped due to when conditional while https://github.com/docker/app/pull/655/files do update dependencies and vendoring
