Subject: [PATCH] LibCore: Include fcntl before using it for non-linux lagom
 builds

SOCK_NONBLOCK is a linux-ism that serenity and linux support. For lagom
builds, we use ioctl/fcntl to get a non-blocking socket the old
fashioned way. Some file re-org unhid the fcntl.h dependency of TcpServer,
so add the header explicitly.
