selftests/bpf: add testcase for TRACING with 6+ arguments
Add fentry_many_args.c and fexit_many_args.c to test the fentry/fexit
with 7/11 arguments. As this feature is not supported by arm64 yet, we
disable these testcases for arm64 in DENYLIST.aarch64. We can combine
them with fentry_test.c/fexit_test.c when arm64 is supported too.
Correspondingly, add bpf_testmod_fentry_test7() and
bpf_testmod_fentry_test11() to bpf_testmod.c
Meanwhile, add bpf_modify_return_test2() to test_run.c to test the
MODIFY_RETURN with 7 arguments.
Add bpf_testmod_test_struct_arg_7/bpf_testmod_test_struct_arg_7 in
bpf_testmod.c to test the struct in the arguments.
And the testcases passed on x86_64:
./test_progs -t fexit
Summary: 5/14 PASSED, 0 SKIPPED, 0 FAILED
./test_progs -t fentry
Summary: 3/2 PASSED, 0 SKIPPED, 0 FAILED
./test_progs -t modify_return
Summary: 1/0 PASSED, 0 SKIPPED, 0 FAILED
./test_progs -t tracing_struct
Summary: 1/0 PASSED, 0 SKIPPED, 0 FAILED
