selftests/bpf: DENYLIST.aarch64: Skip fexit_sleep again

Revert commit 90dc946059b7 ("selftests/bpf: DENYLIST.aarch64: Remove
fexit_sleep") again. The fix in 19d3c179a377 ("bpf, arm64: Fix trampoline
for BPF_TRAMP_F_CALL_ORIG") does not address all of the issues and BPF
CI is still hanging and timing out:

   https://github.com/kernel-patches/bpf/actions/runs/9905842936/job/27366435436

   [...]
   #89/11   fexit_bpf2bpf/func_replace_global_func:OK
   #89/12   fexit_bpf2bpf/fentry_to_cgroup_bpf:OK
   #89/13   fexit_bpf2bpf/func_replace_progmap:OK
   #89      fexit_bpf2bpf:OK
   Error: The operation was canceled.

Thus more investigation work & fixing is needed before the test can be put
in place again.
