Defend against Bleichenbacher's Attack in hal_rpc_pkey_import().
Borrowing an idea from PyCrypto, we substitute CSPRNG output for the
value of a decrypted KEK if the PKCS #1.5 type 02 block format check
fails. Done properly, this should be very close to constant-time, and
should make it harder to use hal_rpc_pkey_import() as an oracle.
