RFR: JDK-8032573

[Jamil Nimeh]

Hello all,

This review fixes a small regression in the generateCertificates() and 
generateCRLs() methods for the CertificateFactory class.  At some point, 
input consisting entirely of non-certificate data ceased to throw 
CertificateException or CRLException and instead returned an empty 
collection.  This restores the exception-throwing behavior, but only 
when the entire stream is non-cert data.  Cases where there is 
leading/trailing text around a valid PEM-encoded certificate or CRL will 
still ignore the leading/trailing data and parse the certificate/CRL 
properly as before.
