After unininstall see if certmonger is still tracking any of our certs.

Rather than providing a list of nicknames I'm going to look at the NSS
databases directly. Anything in there is suspect and this will help
future-proof us.

certmonger may be tracking other certificates but we only care about
a subset of them, so don't complain if there are other tracked certificates.

This reads the certmonger files directly so the service doesn't need
to be started.
