Test win-sshproxy with qemu VM

[lstocchi]

it adds the logic to test win-sshproxy by using a qemu VM with fcos and see if the ssh tunneling between host/guest on the podman socket works as expected.

The qemu VM can also be reused for further extensive testing.

It is based on https://github.com/containers/gvisor-tap-vsock/pull/427
