    oeqa/oetest: Improve subprocess error reporting
    
    Without this, we get to know the command failed and the exit code but
    have no idea how the command failed since we don't get the output by
    default.
    
    This makes it much easier to see what went wrong and stand a chance of
    fixing it.
