Truncate Integrity Check Value to the correct length

According to the RMCP+ spec:

RAKP-HMAC-SHA1 specifies the use of RAKP messages for the key exchange
portion of establishing the session, and that HMAC-SHA1 (per [RFC2104])
is used to create 20-byte Key Exchange Authentication Code fields in
RAKP Message 2 and RAKP Message 3. HMAC-SHA1-96 (per [RFC2404]) is used
for generating a 12-byte Integrity Check Value field for RAKP Message 4.
