verific: Fixes incorrect aldff inference in verific importer 
The following SV module at HEAD imported with verific,

```systemverilog
    module my_module(
      input logic [4:0] a,
      input logic clk,
      input logic enable,
      output logic [4:0] z
    );

    reg [4:0] pipeline_register;
    always @(posedge clk) begin
      pipeline_register <= enable ? a : pipeline_register;
    end
    assign z = pipeline_register;

    endmodule : my_module

```

results in the following output verilog

```systemverilog
/* Generated by 0.36 */

(* top =  1  *)
(* hdlname = "my_module" *)
(* src = "/tmp/temp_directory_zTwd0l/my_input.v:2.12-2.21" *)
module my_module(clk, enable, a, z);
  wire [4:0] _0_;

  ) _1_ (
    .AD(5'hxx),
    .ALOAD(1'h0),
    .CLK(clk),
    .D(_0_),
    .Q(z)
  );
  (* src = "/tmp/temp_directory_zTwd0l/my_input.v:11.28-11.58" *)
  \$mux  #(
    .WIDTH(32'd5)
  ) _2_ (
    .A(z),
    .B(a),
    .S(enable),
    .Y(_0_)
  );
endmodule
```

Yosys is incorrectly infering aldffs due to an incorrect conversion
of logical 1 and 0 SigBits.

My PR unifies the conversion of Verific::Net objects into SigBits using
Yosys' internal representation of special signals like 0,1,x,z. After
my PR these signals are correctly converted into DFFs.
