It depends on your needs and where you got your code.
If you wrote it all yourself, pick any license you want (WTFPL is popular). If you got the code from another source, use whatever the original source says you must use (for code copied and edited from Minetest's own sources, that would be GPL or LGPL).
The same applies to your textures and any other files included with your mod.
Make notice of the license you're using somewhere in the code or text files that come as part of your mod, and when you're ready to post your mod in the forum, declare the license in the post as well.
