kuksa-viss-client: add patch to fix SSL context creation

Add a patch that fixes the context purpose in the SSL context
creation done for the client connection.  On a client, the
purpose needs to be set to server authentication to make newer
versions of Python happy.

+Subject: [PATCH] kuksa_viss_client: fix SSL context creation
+
+With the newer Python and OpenSSL in Yocto kirkstone, specifying
+ssl.Purpose.CLIENT_AUTH when creating the SSL context for the
+connection results in the error:
+
+  Cannot create a client socket with a PROTOCOL_TLS_SERVER context
+
+when trying to connect to a server with the client library.  The fix
+is to instead use ssl.Purpose.SERVER_AUTH, since the context will be
+used by the client to validate the server certificate.
