Skip the SSL_get_certificate() lookup and X509_cmp() DER re-parse in the stapling callback when an SSL_CTX has a single certificate. The shortcut is gated to non-dual-cert builds; under HAVE_NATIVE_DUAL_CERT_SUPPORT a CTX can hold multiple certs where only one has OCSP info, so map size alone cannot identify the negotiated cert. Give certinfo a constructor/destructor so its resources are managed by RAII, and allocate it with make_unique. This consolidates the cleanup that was duplicated across certinfo_map_free and the init error path, and fixes two pre-existing leaks (cid and the BoringSSL cert ref) plus an error path that could delete a certinfo_map still owned by the SSL_CTX.

Switch the per-SSL_CTX certinfo map to store std::unique_ptr<certinfo> so ownership is explicit and the value cleanup is handled by RAII. This removes the manual delete in certinfo_map_free and closes a leak window at the insert site: the old release()-then-insert dropped the pointer if the key already existed or the insert threw, whereas emplace with a move only transfers ownership once insertion succeeds.
