tests: Fix `/status' endpoint tests for new 'modules' section

Now that the `/status` endpoint returns a list of loaded language
modules, e.g

  {
      "modules": {
          "python": {
              "version": "3.12.2",
              "lib": "/opt/unit/modules/python.unit.so"
          },

	  ...
      ...
  }

This broke 'test/test_status.py' in a number of ways

  1) The check for all the object values being 0 at startup is no longer
     true with the modules section.

  2) The find_diffs() check broke trying to subtract strings from
     strings.

So don't include the 'modules' section in the check_zeros() check and in
the find_diffs() check, if we're dealing with strings do a basic
compare returning that value instead.
