96a415b1c0 scalar: Port bitcoin-core/secp256k1#1393 to zkp-specific code (mllwchrry)

Pull request description:

  Add the `SECP256K1_SCALAR_VERIFY` macro to the zkp-specific `secp256k1_scalar_set_u64` function.

  This was missed when upstream PRs bitcoin-core/secp256k1#1373 and bitcoin-core/secp256k1#1393 were merged.
