gpu: nvgpu: unit: propagate fault injection to threads

Browse Source 
Change approach to how the fault injection state is stored to facilitate
propagating fault injection state to child-threads. Rather than each
unit maintaining a thread-local object, there is a thread-local
container stored in the posix-fault-injection itself. This container is
initialized for each test module so that is independent of other other
test modules (for parallel test module execution). When child threads
are created with nvgpu_create_thread(), the fault injection container is
configured for the child.
