[PATCH] init.sh: new module, and add minimal tests of its compare function

[Jim Meyering]

Here's a proposed minimal start at tests for tests/init.sh.
To add a test module, I also had to add a primary module,
so we now finally have an "init.sh" module, and as a next step, I'll
convert all of the Files: tests/init.sh references to module dependencies.
