Fixed lost OpenSSL output with "-t".

The OpenSSL pipe wrote to the final CA bundle file, but the encoded PEM
output wrote to a temporary file.  Consequently, the OpenSSL output was
lost when the temp file was renamed to the final file at script finish
(overwriting the final file written earlier by openssl).
