Add support for new mechanisms, for example SHA3 ones while remoting

[Jakuje]

I think they are visible ok for local operations, but according to my observation, they are lost when they travel through the client-server connection. The example I used, locally shows 79, but if I jump over to remoting, I get only 46 mechanisms:

Not all of the mechanisms are supported by the OpenSC/pkcs11-spy either for now so some show unknown mechanism, but I think the remoting should not strip the basic ones, such as the SHA3, which should not make any difference on the wire from SHA2 for p11-kit.
