roachtest: ssh_problem failed

**Note:** This build has runtime assertions enabled. If the same failure was hit in a run without assertions enabled, there should be a similar failure without this message. If there isn't one, then this failure is likely due to an assertion violation or (assertion) timeout.

Jira issue: CRDB-65805

Read pkg/cmd/roachtest/README.md and inspect test_runner.go:891 around the drain/with-shutdown failure, then review the linked TeamCity artifacts and repeated ssh_problem reports on other branches. Done means the recurring scp/SSH failure is explained and the roachtest no longer reports this failure under the affected conditions.
