Extend EAP-SIM/AKA/AKA' test coverage by setting up another
authentication server instance to store dynamic SIM/AKA/AKA' information
into an SQLite database. This allows the stored reauth/pseudonym data to
be modified on the server side and by doing so, allows testing fallback
from reauth to pseudonym/permanent identity.
