py3: convert content-type to bytes

This fixes the exception:

  TypeError: %b requires a bytes-like object, or an object that
  implements __bytes__, not 'str'

On the line:

  ui.debug('Content-Type: %s\n' % content_type)

And it prevents additional exceptions that use the content_type
variable later.
