oeqa/runtime/ssh: Rework ssh timeout

After the changes to improve this test, we keep seeing image testing ssh
failures, particularly on mips.

It looks like part of the problem is that on a loaded system, 5s is too short
for mips to reliably establish an ssh connection. I've seen logs where it keeps
timing out and fails to work, then the debug code successfully uses ssh later after
everything else fails.

Change the timings/retries to give slow platforms enough time to respond.
