Correct the unicode codes used for tree printing

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

<!-- 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
- [ ] These changes fix #__ (github issue number if applicable).

<!-- Either: -->
- [ ] There are tests for these changes OR
- [x] These changes do not require tests because the tree printing code is untested and this is just a correction of a build fix.

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

These were converted from inline UTF-8 to escape sequences, but the
sequences should be in hexadecimal instead of decimal.
