Description: Fix build compatibility with OpenSSL 4.0
Include <openssl/x509v3.h> in hostname.c and hostname.go before checking
#ifndef X509_CHECK_FLAG_ALWAYS_CHECK_SUBJECT, preventing fallback to
legacy OpenSSL < 1.0.2 code that attempts to directly access opaque
ASN1_STRING fields.
Also add preprocessor guards around deprecated protocol methods
(SSLv3_method, TLSv1_method, TLSv1_1_method, TLSv1_2_method) in shim.c
and ENGINE functions (ENGINE_by_id, ENGINE_init, ENGINE_free,
ENGINE_finish, ENGINE_load_private_key, ENGINE_load_builtin_engines)
in shim.c, shim.h, engine.go, key.go to prevent implicit declaration
and undefined reference errors when building against OpenSSL 4.0.
