fix: detect WSL for talosctl cluster create on Docker

Docker on WSL seems to have same issue as Docker/OS X and
Docker/Windows: container IPs are not routable from the host, so we need
to apply same "magic" by using exposed ports.

WSL `talosctl` binary is built for Linux, so we need to do additional
checks for the platform.
