s_server: Do not use SSL_sendfile when KTLS is not being used
Fix a bug in `openssl s_server -WWW` where it would attempt to invoke `SSL_sendfile` if `-ktls -sendfile` was passed on the command line, even if KTLS has not actually been enabled, for example because it is not supported by the host. Since `SSL_sendfile` is only supported when KTLS is actually being used, this resulted in a failure to serve requests. Fixes #17503.
