    Sync repos to correct location on repo master

    The repo container sync task synchronises the following directories to a
    wrong location.

    pools
    -----
    Wrongly created dir on target: /var/www/repo/{{ repo_build_os_distro_version }}
    Fixed dir on target: /var/www/repo/pools/{{ repo_build_os_distro_version }}

    As the links and other directories are synced successfuly, they point
    to invalid locations which will cause the repo build on the existing
    repo master to fail.

    venvs
    -----
    Wrongly created dir on target: /var/www/repo/{{ repo_build_os_distro_version }}
    Fixed dir on target: /var/www/repo/venvs/{{ repo_build_release_tag }}/{{ repo_build_os_distro_version }}

    os-releases
    -----------
    Wrongly created dir on target: /var/www/repo/{{ repo_build_os_distro_version }}
    Fixed dir on target: /var/www/repo/os-releases/{{ repo_build_release_tag }}/{{ repo_build_os_distro_version }}

    The patch achieves this by creating the directory befor rsync starts.
    Using rsyncs relative option and synchronizing to the remotes root
    / dir does not work due to permissions on /var/.
