Small corrections

1.
A small oversight that needs fixing: forgotten ( braces ) around a list of adding #define-s.  I looked through the entire code, did not find other places where this has happened.

2.
OpenSSL 0.9.8 has void return values for HMAC_xxx functions, so these cannot be mapped to bool.  Because of that, building against 0.9.8 header files fails.  Need to upgrade to 1.0.0 to get that working again.

Questions?
Not sure what the state of SoftHSM2 currently is?  Should it already work flawlessly?
