    Fix verilog and VHDL netlist backends

    These were inadvertently broken when making core gnetlist changes to
    accomodate slotting in spice-sdb. Since the netlist backend is loaded
    before gnetlist has traversed the schematic, the backends must not
    execute any code which queries gnetlist on load. All such work is
    to be done only when gnetlist invokes the (<backend>) method.
