kuksa-viss-client: add Python 3.10 support patch

Add backported patch from upstream to support latest Python 3.10.x in
the kuksa-viss-client recipe, replacing my previous local change which
no longer seems sufficient with 3.10.4.

+Subject: [PATCH] Update kuksa-viss-client to support Python 3.10
+
+SSH checks in Python 3.10 are stricter.
+Using current version with Python 3.10 gives the following error:
+
+Disconnected!! Cannot create a client socket with a PROTOCOL_TLS_SERVER context (_ssl.c:801)
+
+Changing to default context (i.e. implictly Purpose.SERVER_AUTH)
+Also ignoring hostname check as certificate does not include correct hostname
+Updating Docker build to use Python 3.10

-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.
