Jan Lindemann 910f10b194 lib.util.run_cmd(): Remove parameter interactive
run_cmd() is a thin layer over the public ExecContext API, which
falls back to using a Local instance if not other ExecContext is
specified explicitly. Both the default Local context as the
subsequent call to run() should have the same idea about
interactivity, so allowing to specify it in two parameters
("interactive" and "cmd_input") is a bad idea. Remove "interactive".
