[Fix] bin/tape: ignore options on windows

The current version of `glob` returns paths always with forward slashes, even on windows. This causes the `dotignore` `Matcher` to never match the paths on windows, because it expects backslashes on windows. This means that the `--ignore` and `--ignore-pattern` options do not work properly on windows.

This is fixed in a newer version of glob (not sure which specific version). However, we can not upgrade because it drops support for older node versions that we still want to support in tape. So instead, a workaround is to correct the slashes ourselves.

This issue is already covered by existing test cases (test/ignore-pattern.js), that are currently failing when they are ran on windows. For example: `.\node_modules\.bin\tap test/*.js`. However, an additional fix is needed to make these tests pass (see next commit).
