Fix Cadence Incisive compile errors; VCD-Plus is a VCS-only format

Browse Source 
This fixes the following compile warnings and simulation errors:

Compile-time warnings:
      $vcdplusfile(vcdplusfile);
                 |
ncelab: *W,MISSYST (/home/scottj/rocket-chip/vsrc/TestDriver.v,42|17): Unrecognized system task or function: $vcdplusfile (did not match built-in or user-defined names) [2.7.4(IEEE Std 1364-2001)].
      $vcdpluson(0);
               |

ncelab: *W,MISSYST (/home/scottj/rocket-chip/vsrc/TestDriver.v,44|18): Unrecognized system task or function: $vcdplusmemon (did not match built-in or user-defined names) [2.7.4(IEEE Std 1364-2001)].
        `VCDPLUSCLOSE
                    |
ncelab: *W,MISSYST (/home/scottj/rocket-chip/vsrc/TestDriver.v,89|20): Unrecognized system task or function: $vcdplusclose (did not match built-in or user-defined names) [2.7.4(IEEE Std 1364-2001)].

Which then become simulation-time errors:
