fe-secure.c provides dummy implementations for non-SSL builds, and have a dummy
PQsslKeyPassHook_type implementation there. So either the dummy needs to be
removed if we want this hook OpenSSL specific as well, or the USE_OPENSSL
guards from 9e24109f1a4e4d8d1d keeping them only for openssl_tls_init_hook.
