openssl: handle newer version with ifdefs
openssl: handle newer version with ifdefs

For newer versions of openssl, the OpenSSL_add_all_*() functions
have been replaced with OPENSSL_init_crypto(), so handle that
with the appropriate ifdef, instead of skipping openssl all
together if the version was older.
