33 test failures on windows due to diff_test case sensitivity issue

[peakschris]

33 tests are failing on windows because skydoc is writing CRLF line endings, whilst the expected files are in repo with LF endings.

bazel --windows_enable_symlinks test //doc/shlib:execute_binary.md_difftest --enable_runfiles
