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.
