kunit: Add 'kunit_shutdown' option
Add a new kernel command-line option, 'kunit_shutdown', which allows the user to specify that the kernel poweroff, halt, or reboot after completing all KUnit tests; this is very handy for running KUnit tests on UML or a VM so that the UML/VM process exits cleanly immediately after running all tests without needing a special initramfs.
