wireguard: add processing of received cookie messages
Type: feature
Currently, if a handshake message is sent and a cookie message is
received in reply, the cookie message will be ignored. Thus, further
handshake messages will not have valid mac2 and handshake will not be
able to be completed.
With this change, process received cookie messages to be able to
calculate mac2 for further handshake messages sent. Cover this with
tests.
