d/rules: use new dh option names

From man pages:
  Note that the --no-restart-on-upgrade alias is deprecated and
  will be removed in compat 11.  This is to avoid confusion with the
  --no-restart-after-upgrade option.  The --no-stop-on-upgrade
  variant was introduced in debhelper 10.2 (included in Debian
  stretch).

Follow that to be ready for compat 11 in that regard.
