Dennis Chen c82f8abc80 Clean the teardown process of network test ...

We need to clean the resources created in some test cases, else
in some cases we'll get below error for other tests:

> FAIL: docker_experimental_network_test.go:37: DockerNetworkSuite.TestDockerNetworkMacvlanPersistance
>  docker_experimental_network_test.go:44:
> ...
> Command:  ip link add dm-dummy0 type dummy
> ExitCode: 2
> Error:    exit status 2
> Stdout:
> Stderr:   RTNETLINK answers: File exists
> ...

Logically, each test case should be independent, the failure of previous
test case should not have side-effect for the test cases followed.
