Rename config to openssl-easyrsa.cnf

This clarifies the use of the file as specific to EasyRSA while also
closing the loop on the openssl version chase.  No reason to have a
configuration file that is specific to openssl version at this point.
If the need arises, we'll do so in a sane fashion.

Resolves #159
