Dmitri Shuralyov d04c33d1d0 cmd/godoc: check if server exited when waiting
Previously, the waitForServer family of helpers would wait anywhere
between 15 seconds to 2 minutes for the server to become ready.
But if there's a problem that results in the server exiting early,
that wasn't being detected quickly.

This change modifies tests to also wait for command to exit,
and fail the test quickly if so. This helps during development.

Updates golang/go#33655
