gnu: widelands: Update to 1.0.

* gnu/packages/games.scm (widelands): Update to 1.0.
[source]: Download from github as there is no tarball for v1.0 on their
website.
[inputs]: Add curl.
* gnu/packages/patches/widelands-system-wide_minizip.patch: Adjust for
1.0. CmakeLists.txt now already defines CMAKE_MODULE_PATH, so I've moved
FindMinizip.cmake to this path.
