pkgs.formats: toINIWithGlobalSection wrapper

The new format is based on the existing wrapper and generates an INI file with an unnamed global section at the top as is used by *stunnel* for instance.
Technically the INI format is a subset of this however testing, type checking, and API guarantees profit from two separate generators.
