Jouni Malinen 689a248260 eapol_test: Move Message-Authenticator attribute to be the first one 
Even if this is not strictly speaking necessary for mitigating certain
RADIUS protocol attacks, be consistent with the RADIUS server behavior
and move the Message-Authenticator attribute to be the first attribute
in the message from RADIUS client.
