Auto merge of #12793 - anholt:webgl-linux-expected-update, r=emilio

Remove expected-crash state of many WebGL tests on Linux.

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

Clear the expected-crash state on some webgl tests on linux, to reduce the diff necessary when enabling webgl testing on Linux again.

<!-- 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 changes are to test expectations.

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

These tests are still all skipped currently (see #9331), but with
skipping removed, these didn't crash with Mesa 12.1 on Haswell
(Intel).
