Fix getting CRL

OpenSSL 3.X pretty prints certificates in a slightly different way than previous versions, and this breaks the code for getting the URIs from the CRLDP extension.
This commit fixes the issue by having awk search for additional possible strings to start the CRL Distribution Points output. Unless the CRLDP extension is malformed, it will begin with "Full Name", "Relative Name", "Reasons", or "CRL Issuer".
