m68k: sun3/sun3c: use legacy_timer_tick

These two are different from all other machines: * sun3 does not call timer_routine() but open-codes it except for the profile_tick() call that appears to be unintentionally missing. * sun3x has a commented-out timer irq handler but no functional timer tick I could find. Change both to calling the new legacy_timer_tick here, which includes the call to profile_tick() but does not fix sun3x as that is still commented out.
