internal/task: log buildlet output in chunks

Rather than buffering buildlet output and only showing it in case of
error, stream it to a user-supplied Writer. In relui, buffer 10
seconds of output, or up to 1MB, then dump everything up to the most
recent newline to the logger.

For golang/go#54134.
