Write bytestrings when calling wsgi_write_chunkbug/21

httpservers writes an empty string or an internal server
error message, these needs to be bytes in python 3.

It might have been useful to have wsgi_write_chunk accept
either bytes or strings and do the right thing, but that
seemed too invasive to be safe.
