scripts/xls_to_doc.py: make pylint happy

Pylint is too picky. Still, it is useful to run it, as sometimes
it could point to real issues.

So, let's make it happy by:
- disabling R0902, which is one of those "too many" warnings
  (IMO, it doesn't make sense to limit the number of times some
  thing can be used inside a code;

- disabling another warning about not using .items(). On that
  particular case, IMO it will make the code less clearer for
  reviewers and future maintainership, e. g.:

	test_nr = self.tests[testname].get("Test")

  and similar occurrences for self.tests[testname] is a lot clearer
  than:

	for testname, value in self.tests.items():
		...
		test_nr = value.get("Test")
		...
		value["subtests"][subtest][k] = val

	(and other similar occurrences)

  ok, a better name than "value" might help, but still the
  obvious choice would be "test", "test_testname" and such,
  which just makes the code more obfuscated.

  So, ignore the warning for good.

- remove a blank line before a docstring comment;

- remove a currently unused argument from update_files;

- fix indent on a single line.

No functional changes.
