GUACAMOLE-839: Use BouncyCastle for retrieval of certificate details.

Java's build-in support for reading X.509 certificates does not deal
well with PIV certificates containing the username as a "serialNumber"
attribute. Rather than exposing the string value of that attribute, the
Java implementation exposes a byte array that does not fully match the
string value shown by a tool like OpenSSL.

BouncyCastle, on the other hand, _does_ match the output of OpenSSL, and
provides a predictable means of decoding the certificate.
