multimedia/emby-server: upgrade 4.0.2.0 -> 4.1.1.0

• Build the ffmpeg with gcc to streamline with the bundled ffdetect binary
• Remove the update tarball from the rc script as we update through ports and don not want people getting mismatched checksums by updating this way
• Streamline configure target: explicitly disable autodetected libraries that are unwanted
• Remove X11 requirement & gettext-runtime (not needed anymore)
