Subject: [PATCH] apparmor: advertise the tcp fast open fix is applied

The fix for tcp-fast-open ensures that the connect permission is being
mediated correctly but it didn't add an artifact to the feature set to
advertise the fix is available. Add an artifact so that the test suite
can identify if the fix has not been properly applied or a new
unexpected regression has occurred.
