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@linux bpf]# echo 0 > /proc/sys/net/core/bpf_jit_enable
  [root@linux 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@linux bpf]# ./test_verifier 106

  Summary: 0 PASSED, 1 SKIPPED, 0 FAILED
