Permanently disable xss auditor.

Minimal code change to get new behaviour so that tests can
be updated. Code cleanup in a subsequent CL.

The third_party/blink/web_tests/http/tests/security/xssAuditor
directory is removed entirely. Three other files outside this
directory are removed which also triggered the auditor.
