test_description='Test with test-tool submodule is-active

This test verifies that `test-tool submodule is-active` correctly identifies
submodules which are "active" and interesting to the user.

This is a unit test of the submodule.c is_submodule_active() function,
which is also indirectly tested elsewhere.
