pcbnew: Remove all threading from dynamic ratsnest 

The last remaining threaded operation in dynamic ratsnest was the
recalculation of the dynamic connectivity map.  Because we do not
require any of the extra features of the connectivity map, we can get
away with a lightweight move of the anchors to update the ratsnest.  The
resulting connectivity tree is not valid but it is not needed for the
ratsnest, which only needs a list of nets/anchors.
