test: update reference images for new cloudooo

Since https://lab.nexedi.com/nexedi/slapos/commit/0aaa1ccd14f65c8b5d2ec1297309c9d7518f1c53 cloudooo fonts are now configured correctly. The snapshots from these tests have been expecting the old, wrong fonts.

This update snapshots to use the new fonts, so that we can update production cloudooo used for tests.
