The purpose here is to force EasyRSA find the required data-files:
* 'openssl-easyrsa.cnf' MUST be found.
* 'x509-types' MUST be found.
* 'vars.example' should be found.
* 'vars'
The 'vars' file is more complicated due to user expectations.
This patch does not copy 'vars', the code is included but DISABED.
The reasons are:
* Allow running 'easyrsa' from PATH.
* Make standard packaging work correctly.
Bug fixes:
* #499 and associated issues with missing files.
