perf record: Put new line after target override warning

There's no new-line after target-override warning, now:

  $ perf record -a --per-thread
  Warning:
  SYSTEM/CPU switch overriding PER-THREAD^C[ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.705 MB perf.data (2939 samples) ]

with patch:

  $ perf record -a --per-thread
  Warning:
  SYSTEM/CPU switch overriding PER-THREAD
  ^C[ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.705 MB perf.data (2939 samples) ]
