nettle: port upstream hardening of EC point multiplication
Some internal functions used in point multiplications are known to
misbehave if the scaler is out-of-range. This performs canonical
reduction on scalers, before point multiplication.
This ports the fixes from Nettle upstream to the bundled EC code.
See the Nettle 3.7.2 release announcement for details:
