Fix BEV_IS_SSL() macro

We cannot use the same trick with external declaration,
since there are copy of bufferevent_ops_ssl in each library:
- openssl
- mbedlts

However we can just compare the name of the bufferevent type for now.
(It is totally fine to use memcmp() here since it will be optimized by the compiler).
