[PATCH] kconfig: Fix variable name typo in streamline_config.pl.

[hiromu yagura <hiromu1996@gmail.com>]

When I added "use strict;" to streamline_config.pl, I saw following
warnings.

> Global symbol "%prompt" requires explicit package name at
scripts/kconfig/streamline_config.pl line 183.
> Global symbol "%prompt" requires explicit package name at
scripts/kconfig/streamline_config.pl line 368.

Let's fix it.
(Note: prompts[] is defined at line 123 but never used. This seems
typo.)
