[wpa_supplicant] EAP-SIM send AT_IDENTITY first

For EAP-SIM connections, reorder the order of the attributes in
EAP-Response/SIM/Start message: Send AT_IDENTITY first, then
AT_NONCE and AT_VERSION instead of AT_IDENTITY last. Even though there
is no order requirements in the RFC, some implementations expect the
order of the attributes to be exactly as described in the RFC figures.
