Fix setSingleTrackSelectionBit not setting notBadMcTrack bit

setTrackSelectionBit defaults setNotBadMcTrack=true, but
setSingleTrackSelectionBit (the only bit-builder used for JTrackSub,
in eventwiseConstituentSubtractor.cxx) never sets it. Since
selectTrack() gates unconditionally on notBadMcTrack, every
event-wise constituent-subtracted track fails selection regardless
of configured trackSelections, silently zeroing all downstream
subtracted-jet finding.

This brings setSingleTrackSelectionBit in line with the existing
default behavior of setTrackSelectionBit.
