multimedia/lives: Improve port

• Fix build with FFMPEG option, but mark it BROKEN: "Crashes at runtime if the FFMPEG option is enabled".
• Replace PORTVERSION with DISTVERSION.
• Merge gettext-runtime and gettext-tools to gettext in USES.
• Split long OPTIONS_DEFINE.
• Remove NLS from OPTIONS_DEFINE - NLS is enabled by default by ports framework.
• Remove NLS_USES=gettext-tools - gettext already in USES.
• Refresh patch-jack1.
