    Run wheels build for each unique distro/arch

    There may be multiple architecures and OS versions in
    ansible_play_hosts. However, with run_once we build wheels only
    for one selected distro and do not repsect multi-arch/multi-distro
    setups.
    Instead of run_once we need to select single (and first in play)
    host of each architecture and distro and delegate wheels building
    from it. That is needed, because venv_build_host is selected based
    on the facts gathered for current inventory_hostname and will
    depend on it's arch/distro.
