selftests/bpf: add helpers for KASAN in JIT testing

Add two simple helpers to allow checking whether KASAN for eBPF tests
should be executed:
- one helper to check if BPF_JIT_KASAN is enabled in kernel
  configuration
- one helper to check if the kernel is running with kasan_multi_shot
  (otherwise only the first test will be able to trigger a report)
