unified/sysgen: do not generate TICK_EVENT event
Sysgen was still generating the TICK_EVENT event needed for the
microkernel system clock timer driver in the unified kernel. That ended
up dragging in alerts all the time, which in turns drag in the system
work queue, which drags in the work queue, which drags in FIFOs.
This shaves 1052 bytes of RAM and 860 bytes of ROM in systems that don't
need these components (on x86 with IAMCU).
