sql:cli fails in containerized environments (Docker, ddev) - false positive stdin detection and missing TTY

When SSH'd into a server and running drush sqlc (directly or via ddev), Drush can't detect the TTY properly; this is evident with ```drush sqlc``` which exits immediately without landing at a prompt.

In my case, I'm ssh'd into a local user and running ddev under that user, so multiple levels of ssh.
