Add MarkHttpAsDangerous test and correct other MarkNonSecureAs tests

In ssl_browser_tests.cc, we have various tests that CreateFieldTrial
with kMarkHttpAsDangerous. This field trial is overridden by the
fieldtrial_testing_config.json settings and therefore these calls
are ineffective. This CL overrides the fieldtrial_testing settings.

We also didn't have a test that actually tests that the setting
MarkHttpAsDangerous marks HTTP as dangerous. This CL adds such
a test.
