StarlingX 3.x branch fails to download due to mock upgrade to python3

[Saul Wold]

The stx.3.0 branch fails to build due to the same issue that was encountered in master with the recent mock upgrade in CentOS repos. This patch [0] was applied to master but not yet backported to the stx.3.0 branch.

Severity is High due to blocking the stx.3.0 build.

Reproduce by running build-pkgs with an freshly created build Docker container.

    Dockerfile: pin centos & epel repo versions

    Avoid different outcomes every time we run "docker build":

    - Use centos 7.8 base image
    - Use fixed versions of CentOS & EPEL repos
    - Pin mock & its dependencies to 1.4.16
    - Don't install unnecessary packages
    - Don't install unnecessary/conflicting repo files

    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.

    Update the docker image tag to 7.8

    Since the base centos images now is 7.8.2003, updated the
    TC_CONTAINER_TAG variable in the tb.sh script to reflect the same.

    download_mirror.sh needs sudo to run some commands

    If download_mirror.sh is not run by root or under sudo,
    and if -n was omitted, then chown and some rm commands
    performed internally by download_mirror.sh will need sudo.

    The non-root user would need to be permitted to use those
    commands in sudoers.
