gpu: nvgpu: Use single threaded unit testing

Browse Source 
The parallel unit testing is simply too buggy due to unit tests
not being completely independent. We need to determine exactly
what they are sharing and get rid of that.

For now, force unit tests to run one at a time. This should help
avoid many of the race conditions we see.
