tracing: combine the default tracers into one config 

Both event tracer and sched switch plugin are selected by default
by all generic tracers. But if no generic tracer is enabled, their options
appear. But ether one of them will select the other, thus it only
makes sense to have the default tracers be selected by one option.

[ Impact: clean up kconfig menu ]
