Increase commonName_max of openssl.cnf

With a long FQDN, default cert generation from our postinstall fails with the following:

string is too long, it needs to be no more than 64 bytes long

So then start up after install fails out of the box with the following error:

SSLCertificateFile: file '/opt/rh/jbcs-httpd24/root/etc/pki/tls/certs/localhost.crt' does
not exist or is empty

Would we consider increasing commonName_max in our openssl.cnf?
