TrackCosmicsExt.Reader pushes TF ID info only if explicitly requested

The content of tfID branch written in the TrackCosmicsExtended tree is identical to TimingInfo provided by DPL from
the o2_tfidinfo.root tree. By default the corresponding input {GLO,COSMFULLTFID,0} will be skipped, can be
requested via --push-tfid-info option.
