For some code that is tested using public APIs it's not safe for the
parent thread to continue while the child thread is running. Fault
injection per thread pointer points to the same container for both
parent thread as well as the created one. So, there is chance of a race
in fault injection functionality. Serialize the run so that race can be
mitigated. Caller of nvgpu_thread_create() API should ensure that the
created thread is stopped using some fault injection or otherwise.

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.

As per one of the requirement priority of interrupt threads in
qnx should be changed to 21 with SCHED_RR class. NVGPU driver
is creating threads with FIFO class. This makes delay in scheduling
other interrupt threads.
This is added to change the schduler class to RR.
