selftests/bpf: Enable tests for atomics with cpuv4

When looking at Alexei's patch ([1]) which added tests for atomics,
I noticed that the tests will be skipped with cpuv4. For example,
with latest llvm19, I see:
  [root@arch-fb-vm1 bpf]# ./test_progs -t arena_atomics
  #3/1     arena_atomics/add:OK
  ...
  #3/7     arena_atomics/xchg:OK
  #3       arena_atomics:OK
  Summary: 1/7 PASSED, 0 SKIPPED, 0 FAILED
  [root@arch-fb-vm1 bpf]# ./test_progs-cpuv4 -t arena_atomics
  #3       arena_atomics:SKIP
  Summary: 1/0 PASSED, 1 SKIPPED, 0 FAILED
  [root@arch-fb-vm1 bpf]#

It is perfectly fine to enable atomics-related tests for cpuv4.
With this patch, I have
  [root@arch-fb-vm1 bpf]# ./test_progs-cpuv4 -t arena_atomics
  #3/1     arena_atomics/add:OK
  ...
  #3/7     arena_atomics/xchg:OK
  #3       arena_atomics:OK
  Summary: 1/7 PASSED, 0 SKIPPED, 0 FAILED
