Remove test exceptions for even more tests that have "healed" themselves

I have checked that these tests "unexpectedly" pass in
https://test-results.appspot.com/data/layout_results/Linux_Tests/68204/site_per_process_webkit_layout_tests/layout-test-results/results.html:
(and also in 68203 and 68202 and 68201), so let's try reenabling these
tests.

I have also tried 5 runs on linux_chromium_rel_ng trybot and all the
removed tests have passed there as well, except
external/wpt/content-security-policy/securitypolicyviolation/upgrade-insecure-requests-reporting.https.html
which I can repro locally and which turned out to be the same as
https://crbug.com/793127.
