Update systemtap trace example scripts
- Update all scripts to use the beam.smp emulator, since the non-SMP one
is gone
- Fix some scripts that had been copied directly from dtrace and were
invalid either for functions or for probe names
- Removed a driver__event probe check since it appears to not exist
