kasan: change kasan_atomics kunit test as KUNIT_CASE_SLOW

During running KASAN Kunit tests with CONFIG_KASAN enabled, the following
"warning" is reported by kunit framework:

	# kasan_atomics: Test should be marked slow (runtime: 2.604703115s)

It took 2.6 seconds on my PC (Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz),
apparently, due to multiple atomic checks in kasan_atomics_helper().

Let's mark it with KUNIT_CASE_SLOW which reports now as:

	# kasan_atomics.speed: slow
