Fix generation of padding message before encrypting Elgamal in pgcrypto fe0a0b5, which has added a stronger random source in Postgres, has introduced a thinko when creating a padding message which gets encrypted for Elgamal. The padding message cannot have zeros, which are replaced by random bytes. However if pg_strong_random() failed, the message would finish by being considered in correct shape for encryption with zeros.
