RpcSensitivieDetectors - Remove never implemented rotation logic
In real ATLAS, half of the chambers were built-in upside down. The GeoModel does not have this flexibility though it's been claimed in the variable names of the sensitive detectors. Yes, that's an intrinsic bias in rpc digitization but I'm pretty convinced that it would just inspire
even more, if he were alive today. On the other hand, the digi is anyhow broken in main.
Anyhow, I'm not expecting any change in the simulation output but let me tag @mbandier, @jchapman, @tlari such that they can press the revert button, if I'm surprisingly wrong and the ART tests trigger.
