ktls: Add tests for receiving corrupted or invalid records.
These should all trigger errors when reading from the socket. Tests include truncated records (socket closed early on the other side), corrupted records (bits flipped in explicit IVs, ciphertext, or MAC), invalid header fields, and various invalid record lengths.
