Disable some vim tests on Windows

Some vim tests fail on Windows because they assume Linux-specific paths.
The test don't seem intended to be portable so disabling the two that
fail seems reasonable. The failures (--upload only) can be reproduced
with this command:

  git cl presubmit --upload --force --files tools/vim/tests/chromium.ycm_extra_conf_unittest.py

The failures were hidden until recently because failures during --upload
presubmits were converted to warnings. That no longer happens during
--presubmit --all or --files testing.
