pcbnew: align centers to the top and left 

When aligning module centers, it can be hard to determine which item
will be chosen for the alignment target when it chooses based on the
median of the center values.  Instead, this patch chooses the alignment
target as the top and left most items of the Y and X centering,
respectively
