Bugfix: cleanup dependency of AlgoOffline on fles_logging

1. AlgoOffline already depends on FairLogger 3 lines above, not sure about the outcome, it may explain some of the build warnings and the lower than I expected reduction in the weekly builds log size
2. There were multiple instances in the algo library were the fles_logging header log.hpp was used instead of the compatibility one, with sometimes a mix in the same folder
3. The NO_ROOT flag was propagated to multiple higher level reco library (steer, offline steer, probably also analysis ones...) through Littrack which was depending on Littrackparallel which itself was wrongly depending on the online KfCore instead of KfCoreOffline. This combined with the includes in the Digi classes to force a dependency on fles_logging in offline libraries which should have only depended on FairLogger

Difference between the last two versions shows how involved the debugging process was (around 10 hours on my side)
