ssh: add test case against ssh CLI

These tests try to ensure better compatibility of our server implementation
with the ssh CLI.

With these tests in place:

1) before merging CL 447757 we would have noticed that our server
   implementation was broken with OpenSSH 8.8+
2) after merging CL 447757 we would have noticed that our server
   implementation was broken with OpenSSH 7.2-7.7

The ssh CLI from $PATH is used by default, but can be overridden using
the SSH_CLI_PATH environment variable.
