Yonghong Song 58d84bee58 bpf: Add type cast unit tests
Three tests are added. One is from John Fastabend ({1]) which tests
tracing style access for xdp program from the kernel ctx.
Another is a tc test to test both kernel ctx tracing style access
and explicit non-ctx type cast. The third one is for negative tests
including two tests, a tp_bpf test where the bpf_rdonly_cast()
returns a untrusted ptr which cannot be used as helper argument,
and a tracepoint test where the kernel ctx is a u64.

Also added the test to DENYLIST.s390x since s390 does not currently
support calling kernel functions in JIT mode.
