tracing: Fix enabling category groups that don't reference known categories

If a trace event category group (e.g., "red,green,blue") doesn't
reference any known individual categories, i.e., all group members are
dynamic, it would previously never get enabled for tracing. This patch
corrects to logic to also evaluate dynamic categories comprising
category groups when deciding which categories are enabled.
