veyron/security,veyron2/security: Use latest security primitives and test libraries.

This commit makes three related changes:
(1) The ACL authorizers are now compatible with the new security primitives
(security.Principal and security.Blessings)
(2) The unittests for the ACL authorizer only use the new primitives (since the
old ones will be deleted soon)
(3) A veyron2/security/sectest package (akin to net/http/httptest) is provided
to make security primitives more easily accesible in unittests.
