kasan: switch kunit tests to console tracepoints
Switch KUnit-compatible KASAN tests from using per-task KUnit resources to
console tracepoints.
This allows for two things:
1. Migrating tests that trigger a KASAN report in the context of a task
other than current to KUnit framework.
This is implemented in the patches that follow.
2. Parsing and matching the contents of KASAN reports.
This is not yet implemented.
