Shift dogleg created from EAST pins (M2) from one P-Pitch left. 

* Bug: In Anabatic::AutoHorizontal::_slacken(), when creating the target
    dogleg, if the target was a fixed pin (M2) on the east side, the
    vertical was put righ on the side, which is *not* an allowed track.
    The exact east side is not covered by a vertical track (this comes
    from a policy adpopted for the GCell, to avoid overlapping tracks
    on the border). So we got an error message when katana tries to
    bind it to a track. Now shift one perpandicular pitch to the *left*
    for the EAST pins.
