Fixing win2lin builds by adding a testRequires to DockerDaemonSuite
The success of the win2lin CI before was really "by chance" on the
DockerDaemonSuite : the DockerDaemonSuite was panicking when starting
the daemon on the first non-skipped test.The suite panicked but as
the error returned from `StartWithBusybox` was nil, the test kept
going and was OK because the client had all the correct environment
variables set up to discuss with the remote daemon.

Then, as the suite panicked, no more test attached on the
DockerDaemonSuite ran (that's why on win2lin, `DockerDaemonSuite` was
only composed by 5 tests !). The really bad thing is, we didn't get
any report of the panic on the suite (go-check hiding something
somewhere).

As DockerDaemonSuite needs to run test on the same host as it's
running, this adds a `SameHostDaemon` requirement to the Suite.

This changes also make sure `TestRestartContainerWithRestartPolicy`
does left weirdies behind it.
