1. Enhance the signing rules to use the spx signing commands added to
hsmtool.
2. Change the PKCS#11 provider from sc-hsm-embedded to opensc.
- sc-hsm-embedded supports RSA3072 and ECDSA P256 signatures, but does
not support CKO_DATA objects.
- opensc supports ECDSA P256 signatures and CKO_DATA objects, but does
not support RSA3072 signatures.
We no longer use RSA3072 signatures for signing code; we _can_ use
CKO_DATA objects to hold SPX keys for signing.
