Subject: [PATCH] Prune ordinary wires in Katana::PowerRails.

* Change: In Katana::PowerRails, in TerminalNetlist cells instances,
    the ordinary nets components where generating obstacles, leading
    to stupid cross blockages between the obstacle generated by the
    component supporting the routing pad and the RP itself.
      Now only take into account supplies and clocks (any layers)
    and blockage layers.
      Fix symbolic benches.
