[PATCH 1/3] tools/parse-options: Add '\n' at the end of error messages

[Ravi Bangoria]

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.
