With synthetic events now a separate config item as a result of 'tracing: Move synthetic events to a separate file', tests that use both need to explicitly check for hist trigger support rather than relying on hist triggers to pull in synthetic events. Add an additional hist trigger check to all the trigger tests that now require it, otherwise they'll fail if synthetic events but not hist triggers are enabled.
