Count number of braces on a line when checking spec links in test-tidy

<!-- Please describe your changes on the following line: -->

Allow more than one brace per line when checking spec links in test-tidy.

We had problems caused  by `if unsafe { ... } {`.

<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: -->
- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [X] These changes have tests.

<!-- Also, please make sure that "Allow edits from maintainers" checkbox is checked, so that we can help you if you get stuck somewhere along the way.-->

<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->
