gnu: retroarch-minimal: Add new search paths.

This makes it possible to locate system files provided by libretro cores, as
well as database and cheat files.

* gnu/packages/patches/retroarch-improved-search-paths.patch: Extend patch.
* gnu/packages/emulators.scm (retroarch-minimal) [native-search-paths]:
Register new search paths for the LIBRETRO_CHEATS_DIRECTORY,
LIBRETRO_DATABASE_DIRECTORY and LIBRETRO_SYSTEM_DIRECTORY variables.
