locktorture: Add raw_spinlock* torture tests for PREEMPT_RT kernels
In PREEMPT_RT kernels, both spin_lock() and spin_lock_irq() are converted
to sleepable rt_spin_lock(). This means that the interrupt related
suffixes for spin_lock/unlock(_irq, irqsave/irqrestore) do not affect
the CPU's interrupt state. This commit therefore adds raw spin-lock
torture tests. This in turn permits pure spin locks to be tested in
PREEMPT_RT kernels.
