InDetTrackSelectionTool: move mutex to make code thread safe (ATLASRECTS-6088)


This MR is implementing one of @jburr 's suggestions to make InDetTrackSelectionTool thread safe. This is a temporary measure, and the tool design might be revisited, but a fix is desired for the R22 Round2 MC pre-production. With the proposed modification, the irreproducibility that we were observing in the tau MT reconstruction seems solved (I ran 6 times a standalone tau reconstruction from ESD, on 1000 events with 10 threads, and diff-root did not find problems).

Cheers, Bertrand
