    Dockerfile: add mirror repos to global yum config

    Copy mirror repo files to /etc/yum.repos.d because tb.sh needs them.
    This change fixes a problem introduced by

      Commit: 78263e8784c5f596af2a20b9c6e214fc6fea4878
      Dockerfile: pin centos & epel repo versions

    that caused centos-mirror-tools/download_mirror.sh to fail when executed
    from a docker container created by tb.sh -- "rpm not found" for most
    packages being downloaded.

    This is because download_mirror.sh without additional arguments expects
    toCOPY/yum.repos.d/ files to have been copied to /etc/yum.repos.d/ in the
    docker container by default.
