radv/ci: don't fail if we get a GPU hang during the test on NAVI10
NAVI10 has been getting flakier and flakier. While we have automatic retries to get around GPU hangs, they still end up with a failed job because our infra flags it as a warning.
Let's ignore gpu hangs on navi10 until they get fixed, at which point we will hopefully be able to catch regressions using pre-merge.
