selftests/bpf: Add BTF dedup tests for recursive typedef definitions

Browse source

Add several ./test_progs tests:
    1.  btf/dedup:recursive typedef ensures that deduplication no
	longer fails on recursive typedefs.
    2.  btf/dedup:typedef ensures that typedefs are deduplicated correctly
	just as they were before this patch.
