keystore: Pass verification token to credstore along with requested auth token.
This is needed because the Secure Areas backing the Identity
Credential HAL may exist in a different environment from where the
auth token is minted. In this case, the Secure Area needs a
verification token to make sense of the timestamp in the auth token.
Getting a verification token is an asynchronous operation so change
the binder method used by credstore to be asynchronous as well.
