selftests/bpf: Trim DENYLIST.s390x
Now that trampoline is implemented, enable a number of tests on s390x. 18 of the remaining failures have to do with either lack of rethook (fixed by [1]) or syscall symbols missing from BTF (fixed by [2]). Do not re-classify the remaining failures for now; wait until the s390/for-next fixes are merged and re-classify only the remaining few.
