Workaround for certmonger's "Subject" representations

Browse Source 
If an OpenSSL certificate is requested in Certmonger
(CERT_STORAGE == "FILE") the "Subject" field of such Certificate
is ordered as received. However, when an NSS certificate is
requested, the "Subject" field takes the LDAP order
(components get reversed). This is a workaround so that the behavior
stays the same.

The workaround should be removed when
https://pagure.io/certmonger/issue/62 gets fixed.
