[engine] Host Tests for host_debug_unopt is flaky #123483
Description
LeakSanitizer crashes unpredictably on various builds. Sample builds:
- https://ci.chromium.org/ui/p/flutter/builders/prod/Linux%20Unopt/10825/overview
- https://ci.chromium.org/ui/p/flutter/builders/try/Linux%20Unopt/27250/overview
I'm not sure if we run automatic flake detection on the engine repo, so pessimistically filing this as P1.
