gnu: minetest: New package module.

Aside from the 'minetest-topic' procedure which will be used
for the 'home-page' field of some packages, this module is
currently empty.  The 'contentdb' importer defined in the
following patches will be used to populate this module.

* gnu/packages/minetest.scm: New file.
* gnu/local.mk (GNU_SYSTEM_MODULES): Add it.
