    Iterate over list of values of PPC packages dict

    Currently as we are iterating over a higher level dictionary
    and it is not possible to access the item.value.url attribute
    directly.

    Alternatively, we could get the values that is a list and
    then iterate over that list to get properly the url and
    checksum variables.

    Also, we are not iterating over the dictionary we alternatively change
    the item.key to galera_server_percona_distro_packages_alt_arch.keys()[0]
    that produces the result as item.key.
