selftests/bpf: Expand skb dynptr selftests for tp_btf
Add 3 test cases for skb dynptr used in tp_btf:
- test_dynptr_skb_tp_btf: use skb dynptr in tp_btf and make sure it is
read-only.
- skb_invalid_ctx_fentry/skb_invalid_ctx_fexit: bpf_dynptr_from_skb
should fail in fentry/fexit.
In test_dynptr_skb_tp_btf, to trigger the tracepoint in kfree_skb,
test_pkt_access is used for its test_run, as in kfree_skb.c. Because the
test process is different from others, a new setup type is defined,
i.e., SETUP_SKB_PROG_TP.
The result is like:
$ ./test_progs -t 'dynptr/test_dynptr_skb_tp_btf'
#84/14 dynptr/test_dynptr_skb_tp_btf:OK
#84 dynptr:OK
#127 kfunc_dynptr_param:OK
Summary: 2/1 PASSED, 0 SKIPPED, 0 FAILED
$ ./test_progs -t 'dynptr/skb_invalid_ctx_f'
#84/85 dynptr/skb_invalid_ctx_fentry:OK
#84/86 dynptr/skb_invalid_ctx_fexit:OK
#84 dynptr:OK
#127 kfunc_dynptr_param:OK
Summary: 2/2 PASSED, 0 SKIPPED, 0 FAILED
Also fix two coding style nits (change spaces to tabs).
