gpu: nvgpu: unit: enable signal handler in single thread

Browse Source 
Until now, using single thread we disable the signal handler to
make it easier to debug crashes. Since we are now using single
threading in GVS, it is better to have the signal handler enabled
by default. This patch introduces a "-d" argument to explicitly
disable the signal handler and thus make local debugging easier.
