If STDOUT or STDERR are attached and the container exits, the streams
will be closed by the daemon while the container is exiting, causing
the streamer to return an error
61b02e636d/cli/command/container/hijack.go (L53)
that gets sent
61b02e636d/cli/command/container/run.go (L278)
and received
61b02e636d/cli/command/container/run.go (L225)
on `errCh`.
However, if only STDIN is attached, it's not closed (since this is
attached to the user's TTY) when the container exits, so the streamer
doesn't exit and nothing gets sent on `errCh`, meaning the CLI execution
hangs receiving on `errCh` on L231.
Change the logic to receive on both `errCh` and `statusChan` – this way,
if the container exits, we get notified on `statusChan` (even if only
STDIN is attached), and can cancel the streamer and exit.
