Corrected the DRC rule checking for metal1 hole area.  It was not
counting obstruction metal layers as part of the metal layers, and
so was ending up flagging thousands of errors in the power rails of
the standard cells, where the contacts (to li) were placed on obstruction
layers as part of the "lef write -toplayer" option.  This would only
show up when using "drc(full)", which runs the minimum hole area check.
