[Fuchsia] Update layout tests expectations

Updated test expectations for some layout tests and also updated some tests
to pass on Fuchsia.

With this change all smoke tests run as expected on Fuchsia locally, but they
require a SwiftShader change for executable memory. Once that change is rolled
I'll enable layout tests on FYI fuchsia bots.
