hw/misc/sifive_test.c: replace exit calls with proper shutdown

This replaces the exit calls by shutdown requests, ensuring a proper
cleanup of Qemu. Otherwise, some connections like gdb could be broken
before its final packet ("Wxx") is being sent. This part, being done
inside qemu_cleanup function, can be reached only when the main loop
exits after a shutdown request.
