kasan: rust: Add KASAN smoke test via UAF
Adds a smoke test to ensure that KASAN in Rust is actually detecting a
Rust-native UAF. There is significant room to expand this test suite,
but this will at least ensure that flags are having the intended effect.
The rename from kasan_test.c to kasan_test_c.c is in order to allow the
single kasan_test.ko test suite to contain both a .o file produced
by the C compiler and one produced by rustc.
