Mark date-proto-generic-invocation as Skip for now

date-proto-generic-invocation has an errorneous expectation. When
a fix for crbug.com/v8/7961 was landed, that led to a test failure.

This CL marks the test for Skip and fix the expectation manually.
See https://test-results.appspot.com/data/layout_results/linux-blink-gen-property-trees/350/layout-test-results/results.html

Once the fix for bug v8:7961 [1] is landed and rolled to Chromium,
the Skip line can be dropped.
