[chutney/master] Change the default mode when creating directories

commit 501dff31d2b0ac60087e4559fa137bc5578cd853 Author: cypherpunks <cypherpunks(a)torproject.org> Date: Fri Feb 24 10:13:52 2017 +0000 Change the default mode when creating directories Every call to `mkdir_p` uses mode 448 which is a sensible default.
