kasan: add another use-after-free test
Add a new use-after-free test that checks that KASAN detects
use-after-free when another object was allocated in the same slot.
This test is mainly relevant for the tag-based modes, which do not use
quarantine.
Once [1] is resolved, this test can be extended to check that the stack
traces in the report point to the proper kmalloc/kfree calls.
