Extends the context system in the test scripts to allow executing commands within a guest. Do this without requiring an existing network in the guest by using socat to run ssh via a vsock connection. We do need some additional "sleep"s in the tests, because the new faster dispatch means that sometimes we attempt to connect before socat has managed to listen. For now, only use this for the plain "passt" tests. The "passt_in_ns" and other tests have additional complications we still need to deal with.
