    oeqa/utils/commands.py: Make a copy of variables in get_bb_vars
    
    The function get_bb_vars will remove items for the list passed
    as the function argument, this will leave the caller with an
    empty list and the function never says it will consume the items.
    
    This hasn't been found before because only get_bb_var uses this
    function.
