Adapt lines to new Velo-matching algorithm

Use Rec!4141 (merged) to essentially remove all background from lines that use the Downstream composite to Velo track matching. The rate is reduced by about a factor 2.5.

Xi and Omega lines are now fully inclusive, removing the loose IP and IPCHI2 cut on velo tracks, to also enable an efficient selection of prompt signals. Also the seed selection and the first stage selection in the matching has been loosened.

Throughput is expected to decrease a little, but should be well under control.
