Wrap libraries into a module of their own

[NathanReb]

Currently all of pkcs11, pkcs11-cli, pcks11-driver and pkcs11-rev is built with (wrapped false).

This is bad on several accounts, first being that it adds a lot of modules to the global namespace and even though most of them starts with P11_ or Pkcs11_ it adds a lot of possible conflicts.
Second is that now we have split it into several packages, it would help to clearly identify them with a top-level module.
