chromeos-setdevpasswd: fix permissions on devmode.passwd
By default, this file gets created with 0644 perms which allows any
non-root user to read it (and thus be able to extract & crack offline).
Make sure we create the file with 0600 perms since only root is allowed
to create it, and only root (via pam) needs to read it.
BUG=chromium:374911
TEST=ran script and checked perms, then checked `sudo` as chronos still worked
