Correct issue with Bouncy Castle code signing

If the Bouncy Castle Crypto libraries are unsigned, issues result with
the Eclipse build, since they rely on the copy that exists in the
libraries copied by the download_file.py script.  As a workaround, use
a genrule in ConvertKey to unsign the JARs manually.
