[OOR-CORS] Reorganize layout test expectations for site-per-process

virtual/outofblink-cors and virtual/outofblink-cors-ns should inherit
existing test expectations. There is a dedicated bug for
virtual/outofblink-cors, https://crbug.com/854630, but that doesn't
make sense as none of them are OOR-CORS specific, so I changed the bug
number.
