games/luanti-mineclonia: add port

Survival sandbox game inspired by Minecraft

You start in a randomly-generated world made entirely of cubes. You
can explore the world and dig and build almost every block in the
world to create new structures. You can choose to play in a “survival
mode” in which you have to fight monsters and hunger for survival
and slowly progress through the various other aspects of the game,
such as mining, farming, building machines, and so on Or you can
play in “creative mode” in which you can build almost anything
instantly.
