When executing the 'clib' integration tests, all the FaucetDockerHostTest tests fail with the following time-out:
======================================================================
FAIL: clib_mininet_tests.FaucetDockerHostTest.test_ping_all (subunit.RemotedTestCase)

Looking at the Docker logs, the following appears:
time="2021-07-27T02:40:16.169301507Z" level=error msg="Handler for POST /v1.41/containers/create returned error: error creating aufs mount to /var/lib/docker/aufs/mnt/ ... xino=/dev/shm/aufs.xino: invalid argument"
I suspect that the AuFS support in the DockerInDocker (dind) environment is not working any more.

We managed to get to the bottom of this - running this test under localtest.sh will cause it to fail. Running it using other mechanisms works fine.
This is due to me forgetting about localtest.sh when I committed d041028.
Recommended fix is adding the missing /var/lib/docker mount to localtest.sh.
