libckteec: add support for ECDH derive

This commit adds support for Elliptic curve Diffie-Hellman key
derivation, a mechanism where each party contributes one key pair all
using the same EC domain parameters.

The mechanism derives a secret value and truncates the result.

Tested with pkcs11_tool -m ECDH1-DERIVE
