  Log Message:
  Fix HPKE and DHKEM for X25519 and X448 on s390x

The IKM was not respected by the s390x specific implementations of X25519 and
X448 keygen.  This caused test failures and wrong results if the PCC
instruction was actually available and supported X25519 and/or X448.

Fixes: 78c44b05945b ("Add HPKE DHKEM provider support for EC, X25519 and X448.")
