pkcs11-tool: Do not set PARAMETER_SET on private key template during key generation

The attribute is defined in the list with the footnote 4 (from Table 13) with the description:

> MUST not be specified when object is generated with C_GenerateKey

This matches what EC_PARAMS have and how they are (correctly) handled.
