Cleanup: XSSAuditor's form[action] tests should be manually executable.
https://bugs.webkit.org/show_bug.cgi?id=111049

Reviewed by Daniel Bates.

We currently check whether we're running in a DRT-like world before
creating user-visible output for XSSAuditor's form[action] tests. This
patch removes that restriction in order to allow manually-run tests
to show some reasonable output.

* http/tests/security/xssAuditor/resources/echo-intertag.pl:
    Drop the 'if (window.testRunner)' from the 'showAction' branch in
    order to allow manually running the test.
