Subject: [PATCH 2/2] lib.generators.toGitINI: added test

Added basic generators.toGitINI test.
Mostly taken from https://github.com/nix-community/home-manager/blob/958c06303f43cf0625694326b7f7e5475b1a2d5c/tests/modules/programs/git/git.nix.
The ${"\t} escape is used so that the lines aren't recognized as "Wrong
indent style".
