[fuchsia] Add LogSink to runners_integration_tests' sandbox

Although fuchsia.logger.LogSink is provided when using
run-test-component, it still needs to be in the sandbox.

Also make indentation consistent.

Bug: 1132147
Test: The following no longer appears in the system log when running run_cast_runner_integration_tests with and without --use-run-test-component: `app#sys#fuchsia-pkg://fuchsia.com/cast_runner_integration_tests#meta/cast_runner_integration_tests.cmx` is not allowed to connect to `fuchsia.logger.LogSink` because this service is not present in the component's sandbox.
