Corrected portcard positions in standard pixfwd cylinder

Modifications to Geometry/TrackerCommonData/data/pixfwdCylinder.xml:
- shifted objects of type "PortCards2" so that the IP-facing edges are lined up with the IP-facing edges of the objects of type "PortCards1"
- in BmO, swapped the positions of PortCards1(copyNumber 2) and PortCards2(copyNumber 1) to reflect actual position of BmO CCU in standard geometry
