* Change: In Katana::Track::addOverlapCost(), if an overlaping segment
is owned by the net *and* is the one we want to insert, do not take
it into account in the shared length.
This case never occured before we introduced the "realign" stage,
as a to be inserted segment, was, by definition, not already
inserted in a track. But in the realign stage, it is. So we should
not account it when computing the insertion cost in the track it
is already in. This was preventing short segments (less than a
pitch) to be correctly re-aligned.
And, as a side effect, preventing the antenna/diodes to work as
intended (diode connected at METAL3 layer while the antenna occur
at METAL2 layer).
