pmcertificatemgr: install openssl configuration file

To work correctly pmcertificatemgr needs a special openssl configuration file in /etc/ssl.
It's already part of the source archive but was never installed. The other needed
configuration bits below the /var/ssl directory are created by a special upstart job which
is package separately with the certificate store.
