[PATCH 04/14] kconfig: print additional new line for choice for redirection

[Masahiro Yamada]

If stdout is redirected to a file, prompts look differently due to
missing new lines.

Currently, conf_askvalue() takes care of this by putting additional
new line, but conf_choice() does not.  Do likewise so that prompts
after 'choice' look properly.
