[PATCH] KEYS: Add optional key derivation parameters for DH

The values computed during Diffie-Hellman key exchange are often used in combination with key derivation functions to create cryptographic keys. Add an interface to configure a key derivation function that will transform the Diffie-Hellman result returned by the KEYCTL_DH_COMPUTE command.
