These tests were failing (both with/without ofono) because iwd
was trying to autoconnect before the autotest had issued a
connect request (causing iwd to return a busy response). To fix
this, autoconnect was explicitly disabled in the config file.
Implemented milenage algorithm in hlrauc.py. Unlike EAP-SIM, the
authentication center must compute several values to give back
to the server (hostapd). This was already done by IWD as the peer
in EAP-AKA, but was also needed on the server side (HLR AuC).
