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.
