[gnome-control-center] background: Remove redundant and unused parameter from add_single_file

    background: Remove redundant and unused parameter from add_single_file
    
    There is no need to pass the source-uri as a parameter as we can get it
    from the file itself. This would help in using the same code paths for
    local and remote pictures.
