[igt-dev] [PATCH i-g-t] .gitlab-ci: Retry `ninja test` 2 times in case of failures

[Arkadiusz Hiler]

Freedesktop CI/CD runners are shared machines with a lot of cores and
they accept many parallel jobs coming from multiple projects. There
are no resources guarantees, which leads to the sporadic slowness.

This makes our `ninja test` fail in extreme cases.

We have already tried to bump the timoeut limit for the slower tests in
e941638ce652 ("runner/tests: Increase the timeout by 10x") which helped
a bit, but we still fail from time to time.

As an extra mitigation let's make the CI do 2 retries (= total of 3
attempts) before finally failing the whole pipeline.
