Kees Cook b370f7eacd lib/tests: Add randstruct KUnit test ...

Perform basic validation about layout randomization and initialization
tracking when using CONFIG_RANDSTRUCT=y. Tested using:

$ ./tools/testing/kunit/kunit.py run \
	--kconfig_add CONFIG_RANDSTRUCT_FULL=y \
	randstruct
[17:22:30] ================= randstruct (2 subtests) ==================
[17:22:30] [PASSED] randstruct_layout
[17:22:30] [PASSED] randstruct_initializers
[17:22:30] =================== [PASSED] randstruct ====================
[17:22:30] ============================================================
[17:22:30] Testing complete. Ran 2 tests: passed: 2
[17:22:30] Elapsed time: 5.091s total, 0.001s configuring, 4.974s building, 0.086s running

Adding "--make_option LLVM=1" can be used to test Clang, which also
passes.
