Jouni Malinen 762e4ce620 EAP-AKA': Update to RFC 5448
There was a technical change between the last IETF draft version
(draft-arkko-eap-aka-kdf-10) and RFC 5448 in the leading characters
used in the username (i.e., use unique characters for EAP-AKA' instead
of reusing the EAP-AKA ones). This commit updates EAP-AKA' server and
peer implementations to use the leading characters based on the final
RFC.

Note: This will make EAP-AKA' not interoperate between the earlier
draft version and the new version.
