Michael Brown 66a2ff442d [tests] Verify ability to sleep the CPU ...

The self-test suite does not currently ever attempt to sleep the CPU.
This is an operation that may fail (e.g. by attempting to execute a
privileged instruction while running as a Linux userspace binary, or
by halting the CPU with all interrupts disabled).

Add a trivial self-test to exercise the ability to sleep the CPU
without crashing or halting forever.
