Trackless variables SiHit information

For the new request from Z' samples more Trackless information should be included.

To get them written out, the Sihit Requested was removed from conditions. Otherwise --steering "doOverlay" would overwrite this and the variables would not be saved.

The change in runtime with/without the preexec&postexec is negligible

The increase in memory was 25% for 10 Events.
