ringct: do not include bulletproof commitments in signed message
Those are not serialized, but are restored from the outPk masks,
so depending on what tries to validate the tx, those commitments
may or may not be filled with valid data at the time. The outPk
masks are already hashed as part of the rctSigBase field.
