Do not renew the IPA CA cert by serial number in dogtag-ipa-ca-renew-agent

Always use the full CSR when renewing the IPA CA certificate with Dogtag. The
IPA CA certificate may be issued by an external CA, in which case renewal by
serial number does not make sense and will fail if the IPA CA was initially
installed as a subordinate of an external CA.
