openvpn-easy-rsa: update to 3.0.4

Upstream renamed openssl-1.0.cnf to openssl-easyrsa.cnf.
However, pkg kept using openssl-1.0.cnf.

Upstream easyrsa searchs for vars, openssl-*, x509-types in the
same directory as easyrsa script. This was patched to revert
back to static /etc/easy-rsa/ directory (as does OpenSUSE).
EASYRSA_PKI still depends on $PWD.

Move easyrsa from /usr/sbin to /usr/bin as root is not needed.
