  Log Message:
  python: Fix a double encoding attempt on an Unicode string

Encoding from 'unicode' to 'str' that has been added to the Stream class
in commit 2254074e3067 ("python: fix python3 encode/decode on Windows")
conflicts with SSLStream which already contains a quirk for pyopenssl
that does the same thing.

This results in a double encoding attempt when SSL is used and we crash
and burn due to:

    buf = buf.encode('utf-8')
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 83: ordinal not in range(128)

Remove the quirk from SSLStream as the base class now does encoding.
