  - [Functest] Push results for functest suite

    Since Functest doesn't post the output to
    the console any more, we need the logs in
    some jobs to troubleshoot.
    Those logs are not stored for functest-suite
    jobs by default.
    This patch enables also lf-virtual2 and 3 where
    some apex verify jobs are using this builder.
