  -----------
  pkcs11-spy: Avoid crash while spying C_GetInterface()

When calling the C_GetInterface(), the spy was trying to change the memory
returned by the underlying pkcs11 module. In cases where it was pointing
to the readonly/static memory, the application crashed.

This changes the C_GetInterface() in a way that it does not return the
original memory of underlying pkcs11 module, but local one with our pointers.
