Change the Chrome OS PKCS #11 module from libopencryptoki.so to libchaps.so.

This CL is part of a larger effort to replace opencryptoki as the PKCS #11 layer in Chrome OS.  In this first phase, libchaps.so forwards requests to a daemon (chapsd) which loads opencryptoki to service the requests.  You can find the Chaps design doc here: https://docs.google.com/a/google.com/document/d/1TQFc6GABKa1JgwUx2hIcxAHQ329fkd03yYlGxhfHQlQ/edit

Change-Id: I42962c4703413039641b6ede40caaf0c97ab900e

BUG=chromium-os:21005
TEST=* Ensure previously existing certs still exist.
     * Import new cert and private key from PKCS12 file.
