perf tools: Add '\n' at the end of parse-options error messages

Browse Source 
Few error messages does not have '\n' at the end and thus next prompt
gets printed in the same line. Ex,

  linux~$ perf buildid-cache -verbose --add ./a.out
   Error: did you mean `--verbose` (with two dashes ?)linux~$

Fix it.
