fix: add gosu to hermes + ssh host key to honcho builder

Hermes: install gosu package so run-multi-gateways.sh's gosu hermes
drop works when USER hermes is set in Dockerfile.

Honcho: add openssh-client + ssh-keyscan to openconcho-builder stage
so SSH host key verification passes during Gitea clone on first build.
