selftests/bpf: Add testcases for tailcall hierarchy fixing
Add some test cases to confirm the tailcall hierarchy issue has been fixed.
On x64, the selftests result is:
cd tools/testing/selftests/bpf && ./test_progs -t tailcalls
327/18 tailcalls/tailcall_bpf2bpf_hierarchy_1:OK
327/19 tailcalls/tailcall_bpf2bpf_hierarchy_fentry:OK
327/20 tailcalls/tailcall_bpf2bpf_hierarchy_fexit:OK
327/21 tailcalls/tailcall_bpf2bpf_hierarchy_fentry_fexit:OK
327/22 tailcalls/tailcall_bpf2bpf_hierarchy_fentry_entry:OK
327/23 tailcalls/tailcall_bpf2bpf_hierarchy_2:OK
327/24 tailcalls/tailcall_bpf2bpf_hierarchy_3:OK
