Subject: [PATCH] github: change container storage driver inside test container

The default overlayfs doesn't work inside the container runner which
causes the test to fail with
  Invalid destination name
  containers-storage:localhost/osbuild-skopeo-test-...:
  'overlay' is not supported over overlayfs, a mount_program is
  required: backing file system is unsupported for this graph driver

Changing the driver to vfs solves the issue.
