Subject: [PATCH] Fix "none" datasource to create output directory.

When src/sbin/cirros-ds calls a datasource it passes a directory
that does not yet exist.  The datasource (/lib/cirros/ds/nocloud)
is expected to create it.

The none datasource was not doing that. As a result, you'd see:

   /lib/cirros/ds/none:
      line 23: can't create .../none/data/instance-id: nonexistent
      line 24: can't create .../none/result: nonexistent directory
