Subject: [PATCH bpf-next] selftests/bpf: Add missing line break in test_verifier

There are no break lines in the test log for test_verifier #106 ~ #111
if jit is disabled, add the missing line break at the end of printf()
to fix it.

Without this patch:

  [root@...ux bpf]# echo 0 > /proc/sys/net/core/bpf_jit_enable
  [root@...ux bpf]# ./test_verifier 106
  #106/p inline simple bpf_loop call SKIP (requires BPF JIT)Summary: 0 PASSED, 1 SKIPPED, 0 FAILED

With this patch:

  [root@...ux bpf]# echo 0 > /proc/sys/net/core/bpf_jit_enable
  [root@...ux bpf]# ./test_verifier 106
  #106/p inline simple bpf_loop call SKIP (requires BPF JIT)
  Summary: 0 PASSED, 1 SKIPPED, 0 FAILED

Fixes: 0b50478fd877 ("selftests/bpf: Skip callback tests if jit is disabled in test_verifier")

I am not sure whether the Fixes tag is necessary, you can remove it
if it is useless, thank you.
